How many no of moles are there in 16 gm of oxygen gas?
To find the number of moles in 16 g of oxygen gas, you need to divide the given mass by the molar mass of oxygen. The molar mass of oxygen (O2) is 32 g/mol. Therefore, 16 g / 32 g/mol = 0.5 moles of oxygen gas.
How you can find the mass of 3 moles of oxygen atoms?
To find the mass of 3 moles of oxygen atoms, you need to know the molar mass of oxygen. The molar mass of oxygen is approximately 16 grams per mole. So, for 3 moles of oxygen atoms, the mass would be 3 moles x 16 grams/mole = 48 grams.
How many moles of oxygen in 10dm3?
No. of moles = mass/relitive molecular mass in this case = 10/16 = 0.625 so that's 0.625 of a mole and a mole of anything contains 6.022 x 1023 atoms = 3.76 x 1023 atoms in 10g of oxygen.
How many moles are in 64 grams of oxygen gas?
64 grams of oxygen gas would be equivalent to 2 moles because the molar mass of oxygen gas (O2) is 32 g/mol (16 g/mol for each oxygen atom). 64 grams/ 32 g/mol = 2 moles.
How many grams of water are made from complete reaction of 2.2 moles of oxygen gas with hydrogen gas?
The balanced chemical equation for the reaction of hydrogen gas and oxygen gas to form water is 2H₂ + O₂ → 2H₂O. This means that 2 moles of water are produced for every 1 mole of oxygen gas. Therefore, 4.4 moles of water are produced from the reaction of 2.2 moles of oxygen gas. To convert moles of water to grams, you would need to use the molar mass of water, which is approximately 18 grams/mol. So, 4.4 moles of water would weigh approximately 79.2 grams (4.4 moles x 18 grams/mol).
What is the mass of 0.2 moles of oxygen gas?
The mass of 0,2 moles of oxygen gas is 6,4 g.
How many moles of oxygen are represent in 0.16 g of oxygen gas?
To find the number of moles of oxygen in 0.16 g of oxygen gas, you first need to determine the molar mass of oxygen (O2), which is about 32 g/mol. Then, you can use the formula moles = mass / molar mass to calculate the number of moles. In this case, 0.16 g / 32 g/mol = 0.005 moles of oxygen gas.
How many no of moles are there in 16 gm of oxygen gas?
To find the number of moles in 16 g of oxygen gas, you need to divide the given mass by the molar mass of oxygen. The molar mass of oxygen (O2) is 32 g/mol. Therefore, 16 g / 32 g/mol = 0.5 moles of oxygen gas.
What mass of oxygen gas contains the same number of moles as 56 gram of Sulphur?
To determine the mass of oxygen gas containing the same number of moles as 56 grams of sulfur, calculate the molar mass of sulfur (32 g/mol) and use it to find the number of moles in 56 grams. Then, since the molar ratio of sulfur to oxygen in a compound is 1:1, this same number of moles of oxygen gas would weigh 32 grams.
How you can find the mass of 3 moles of oxygen atoms?
To find the mass of 3 moles of oxygen atoms, you need to know the molar mass of oxygen. The molar mass of oxygen is approximately 16 grams per mole. So, for 3 moles of oxygen atoms, the mass would be 3 moles x 16 grams/mole = 48 grams.
Magnesium oxide decomposes into magnesium and oxygen If 4.03 of magnesium oxide decomposes to form 2.43 of magnesium what mass of oxygen gas is also released in the reaction?
To find the mass of oxygen gas released, you need to calculate the mass of magnesium oxide that contributed to the formation of 2.43g of magnesium. Molar mass of MgO = 40.3g/mol Molar mass of Mg = 24.3g/mol Calculate the moles of Mg formed and use stoichiometry to find the moles of oxygen reacted. Finally, convert the moles of O2 to grams to find the mass of oxygen gas released.
What is the mass of 2.50 moles of oxygen gas?
The relationship between number of moles and mass is: n = m/MW Where n is the number of moles, m is the mass in grams and MW is the molecular weight (or molecular mass). Subsituting the numbers into the equation: 2.5 mol = m/32 (from O2(g), 16 from each oxygen) m = 2.5 * 32 = 80 grams This also means that there is approximately 1.5 x 1024 molecules of O2 in your sample.
How many moles of oxygen in 10dm3?
No. of moles = mass/relitive molecular mass in this case = 10/16 = 0.625 so that's 0.625 of a mole and a mole of anything contains 6.022 x 1023 atoms = 3.76 x 1023 atoms in 10g of oxygen.
How many moles of oxygen gas are there in 180 L of oxygen at STP?
If the density of oxygen atSTP is 1,429 g/L the mass of 180 L is 257,22 g.If the mole of oxygen (O2) is 15,999 g the number of moles is 16,077.
How many moles are in 64 grams of oxygen gas?
64 grams of oxygen gas would be equivalent to 2 moles because the molar mass of oxygen gas (O2) is 32 g/mol (16 g/mol for each oxygen atom). 64 grams/ 32 g/mol = 2 moles.

So, 4.4 moles of water would weigh approximately 79.2 grams (4.4 moles x 18 grams/mol).
What is the weight of 0.8834 mole oxygen gas?
The molar mass of oxygen gas (O2) is 32 g/mol. To find the weight of 0.8834 moles of oxygen gas, you would multiply the molar mass by the number of moles: 32 g/mol x 0.8834 mol = approximately 28.27 grams.
