How many moles of silicon are in 245 g of silicon?
To find the number of moles in 245 g of silicon, divide the given mass by the molar mass of silicon. The molar mass of silicon is 28.09 g/mol. Therefore, 245 g ÷ 28.09 g/mol ≈ 8.71 moles of silicon.
What is the SI base unit for the amount of substance?
The mass is sometimes informally called the "amount of substance", though this is not very precise. The SI unit for mass is the kilogram.
What is the mass of 0.7891 mol of ferric oxide (Fe2O3)?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
What is the mass of 0.7891 mol of ferric oxide Fe2O3?
To find the mass of 0.7891 mol of ferric oxide (Fe2O3), you need to calculate the molar mass of Fe2O3. The molar mass of Fe2O3 is 159.69 g/mol. Multiply the molar mass by the number of moles to find the mass: 0.7891 mol * 159.69 g/mol ≈ 125.94 g. Therefore, the mass of 0.7891 mol of Fe2O3 is approximately 125.94 grams.
What is the mass of 0.7891 mol of ferric oxide?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
How many moles of silicon are in 245 g of silicon?
To find the number of moles in 245 g of silicon, divide the given mass by the molar mass of silicon. The molar mass of silicon is 28.09 g/mol. Therefore, 245 g ÷ 28.09 g/mol ≈ 8.71 moles of silicon.
What is the SI base unit for the amount of substance?
The mass is sometimes informally called the "amount of substance", though this is not very precise. The SI unit for mass is the kilogram.
What is the SI unit for molar mass?
The SI unit for molar mass is grams per mole (g/mol). It represents the mass of one mole of a substance, which is a convenient way to compare the masses of different substances on a consistent scale.
How do you calculate the number of moles in 2.61 grams of silicon?
To calculate the number of moles in 2.61 grams of silicon, divide the given mass by the molar mass of silicon. The molar mass of silicon is approximately 28.0855 g/mol. So, 2.61 g ÷ 28.0855 g/mol ≈ 0.093 moles of silicon.
Why do we need to convert mass to moles?
Mol is an official unit of concentration in SI, not of mass.The transformation of a concentration expressed in mass per volume in a concentration in moles is at your choice.
How many moles dose 11 grams of silicon contain?
11 g x 1 mol Si/28.0855 g Si= 0.39 mol Si 205g He x 1mol He/4.002602 g He=51.2 mol He
What is the mass of 0.7891 mol of ferric oxide (Fe2O3)?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
What is the mass of 0.7891 mol of ferric oxide Fe2O3?
To find the mass of 0.7891 mol of ferric oxide (Fe2O3), you need to calculate the molar mass of Fe2O3. The molar mass of Fe2O3 is 159.69 g/mol. Multiply the molar mass by the number of moles to find the mass: 0.7891 mol * 159.69 g/mol ≈ 125.94 g. Therefore, the mass of 0.7891 mol of Fe2O3 is approximately 125.94 grams.
What is the mass of 0.7891 mol of ferric oxide?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
How much was atom 2ai2o7si2?
The molar mass of atom 2Al2O7Si2 would be calculated as follows: 2(Al) + 2(O) + 7(O) + 2(Si) = 2(26.98 g/mol) + 2(16.00 g/mol) + 7(16.00 g/mol) + 2(28.09 g/mol) = 404.14 g/mol.
What is the mass in grams of 0.330mol of calcium?
To find the mass in grams of 0.330 mol of calcium, you need to use the molar mass of calcium which is 40.08 g/mol. Mass = moles x molar mass Mass = 0.330 mol x 40.08 g/mol = 13.24 g.
What is the mass of 0.45 mol of ammonium sulfate?
To calculate the mass of 0.45 mol of ammonium sulfate (NH4)2SO4, you need to know its molar mass. The molar mass of (NH4)2SO4 is 132.14 g/mol. Multiply the number of moles (0.45 mol) by the molar mass to get the mass: 0.45 mol x 132.14 g/mol = 59.46 grams. Therefore, the mass of 0.45 mol of ammonium sulfate is 59.46 grams.
