The answer is 0,173 moles.
6,5 moles oxygen equals 208 g.
The equivalent in moles is 6,03.
The answer is 2 moles.
The mass of 0,2 moles of oxygen gas is 6,4 g.
We need 3 moles of potassium perchlorate.
6,5 moles oxygen equals 208 g.
The equivalent in moles is 6,03.
The answer is 2 moles.
The chemical reactin is:2 KClO3 = 2 KCl + 3 O24 moles of potassium chlorate produce 6 moles oxygen.
The mass of 0,2 moles of oxygen gas is 6,4 g.
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.
30 moles
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.
We need 3 moles of potassium perchlorate.
Four moles of potassium chlorate are needed.
The molar mass of oxygen gas (O2) is 32.00 g/mol. Therefore, the mass of 4.00 moles of oxygen gas is 128.00 grams.
1 mole of any gas occupies 22.4 liters at standard temperature and pressure (STP). Therefore, 68.5 liters of oxygen gas at STP would be 68.5/22.4 = 3.06 moles of oxygen gas.
