What is the gram mass of compound if 5 moles of the compound has a mass of 100 grams?
The molar mass is 20 g.
What is 2.5 grams per 100 milliliters in moles per Liter?
To convert grams per milliliter to moles per liter, you need to know the molar mass of the substance. Assuming the substance is water (H2O), its molar mass is 18.015 g/mol. Therefore, 2.5 grams per 100 milliliters is equivalent to approximately 138.6 mmol/L (millimoles per liter) for water.
5.8 grams in 1 liter of water equals how many moles?
To convert grams to moles, divide the mass in grams by the molar mass of the substance. The molar mass of water is approximately 18 g/mol (1 g/mol for hydrogen and 16 g/mol for oxygen). So, 5.8 grams of water in 1 liter would be approximately 0.32 moles (5.8 g / 18 g/mol).
How many moles aluminum exist in 100.0 grams of aluminum?
The formular you need is M = n/m (molar mass = amount of substance/mass), or n = m/MAluminium has a molar mass of 26.982 g/mol. The given mass is 3 grams. Therefore:n(Al) = 3g / (26.982g/mol) = 0.11mol
What mass of NaOH is required to make up 100 mL of a 0.5000 M solution?
Two parts.Molarity = moles of solute/Liters of solution ( 100 mL = 0.1 Liters )0.5000 M NaOH = X moles/0.1 L= 0.05 moles NaOH--------------------------------now,0.05 moles NaOH (39.998 grams/1 mole NaOH)= 1.99 grams NaOH required====================( could call it 2.00 grams )
How many moles of phosphorus atoms are in 100 grams of P4S10?
To find the number of moles of phosphorus atoms in 100 grams of P4S10, we first need to determine the molar mass of P4S10 which is 284.26 g/mol. Next, we calculate the number of moles of P4S10 in 100 grams by dividing 100 g by the molar mass to get 0.352 moles of P4S10. Since there are 4 phosphorus atoms in each P4S10 molecule, there are 0.352 moles x 4 = 1.41 moles of phosphorus atoms in 100 grams of P4S10.
How many grams CS2 with 100 grams of S8?
To determine the amount of CS2 that can be produced from 100 grams of S8, we need to first convert 100 grams of S8 to moles using the molar mass of S8 and then use the balanced chemical equation to find the moles of CS2 produced. Finally, we convert moles of CS2 to grams using the molar mass of CS2.
100 grams of ammonia equals how many moles?
For this you need the atomic (molecular) mass of NH3. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. NH3=16.0 grams100 grams NH3 / (16.0 grams) = 6.25 moles NH3
What is the mass of 100 millimoles of caffenine C8H10N4O2?
100 millimoles is 0.1 moles. To convert moles to grams, you need to multiply by the molecular weight, in this case, 194.22g/mol. 0.1*194.22 is 19.422 grams.
How many grams atoms are in 100 of sulfur?
The molar mass of sulfur is approximately 32 grams per mole. Therefore, 100 grams of sulfur would contain approximately 3 moles of sulfur atoms (100 grams / 32 grams/mole). To find the number of atoms, you would then multiply the number of moles by Avogadro's number (6.022 x 10^23 atoms/mole) to get the total number of sulfur atoms in 100 grams.
How many moles of sodium borohydride are used in 100 mg?
To calculate the number of moles of sodium borohydride in 100 mg, you need to know the molar mass of the compound, which is 37.83 g/mol. First, convert 100 mg to grams (0.1 g), then divide by the molar mass to get the number of moles, which is approximately 0.0026 moles.
How many atoms does 100 grams of gold have?
To find the number of atoms in 100 grams of gold, you would first calculate the number of moles using the molar mass of gold (197 grams/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. So, approximately 3.01 x 10^23 atoms of gold are present in 100 grams.
What is the number of moles in 100 g MgCO3?
To calculate the number of moles in 100 g of MgCO3, you need to first determine the molar mass of MgCO3, which is 84.31 g/mol. Divide the given mass (100 g) by the molar mass to find the number of moles. In this case, 100 g / 84.31 g/mol ≈ 1.19 moles of MgCO3.
How many moles of water are there in 100 grams of water?
First you find the Molar Mass of water using the values on the periodic table.2 Hydrogen + 1 Oxygen2*1.01 + 16.00 = 18.02 g/molThen using factor-label to cancel out units(100g H2O)*(1 mol H2O / 18.02 g H2O) = 5.54938957 molSo the number of moles in 100g of H2O is about 5.55 moles.Hope that helps.
How do you solve for how many grams are in 2.38 moles of calcium carbonate?
To convert moles to grams, you need to use the molar mass of calcium carbonate (CaCO3). The molar mass of CaCO3 is approximately 100.1 g/mol. To calculate the grams in 2.38 moles of CaCO3, you would multiply the number of moles (2.38) by the molar mass (100.1 g/mol), which gives you approximately 238 grams.
What is the gram mass of compound if 5 moles of the compound has a mass of 100 grams?
The molar mass is 20 g.
What is 2.5 grams per 100 milliliters in moles per Liter?
To convert grams per milliliter to moles per liter, you need to know the molar mass of the substance. Assuming the substance is water (H2O), its molar mass is 18.015 g/mol. Therefore, 2.5 grams per 100 milliliters is equivalent to approximately 138.6 mmol/L (millimoles per liter) for water.
