1 mole O2 weighs 32 g
so 64 g O2 is 2 mol O2 gas
which has 2 X 6.022 X 1023 = 1.2066 X 1024 molecules of O2

How many oxygen molecules are there in in 4 g of oxygen?
Assuming you mean oxygen gas, the number of molecules can be found by first finding the number of moles = mass of oxygen (4g) / Molecular mass of oxygen gas (32 g mol-1) This tells us there is 0.125 mol of oxygen gas present. The number of molecules present is given by the number of moles x the avogadro constant (6.022x10^23) So the number of oxygen gas molecules present is equal to 0.125 x 6.022x10^23 = 7.5275x10^22 molecules
How many oxygen molecules are in 9.1 L of oxygen gas at STP?
at stp 1 mole of a gas contains 22.4 litres. 9.1/22.4= .40625 moles o2. 1 mole of a gas contains 6.022E23 molecules so .40625 moles x 6.022E23 = 2.4464325E23 molecules, but you have to multiply by two due to it being diatomic, so answer x 2 = 4.892875E23 molecules
How many molecules of ammonia can be formed from the reaction of 2 molecules of Nitrogen gas and 6 molecules of hydrogen gas?
The chemical equation is N2 + 3H2 -> 2NH3 So reacting 2 moles of N2 will produce 4 moles ammonia.
How many moles of oxygen are represent in 0.16 g of oxygen gas?
using the equation moles=mass/molar mass (since its in gas form) O2 => 16*2 =32 0.16/32=0.005 moles :)
How many moles of oxygen gas are needed to react with 10.0 mol of ammonia?
4NH3 + 3O2 -----> 2N2 + 6H2O 4 moles of ammonia react with 3 of oxygen. So 10 moles of ammonia requires 7.5 moles of oxygen.
If 4.8g of oxygen gas is completely converted to ozone how many molecules of ozone would be produced?
4.8/16 moles of oxygen atoms converts to 1.6/16 moles of ozone molecules.

How many moles of oxygen gas are needed to make 4 moles of water?
4 moles of oxygen atoms are present in 4 moles of H2O

How many oxygen molecules are present in 113.97 liters of oxygen gas at STP?
At STP, one mole of any gas occupies 22.4 liters. This is called molar volume. 113.97 liters ÷ (22.4 L/mol) = 5.09 moles Then convert moles to molecules (1 mole = 6.02 × 1023 molecules) 5.09 moles × (6.02 × 1023 molecules/mol) = 3.06 × 1024 molecules
How many moles are in 5.56g of oxygen gas (O2)?
The answer is 0,173 moles.
Which quantity of o2 contains exactly 3.01x1023 molecules?
3,6 x 1023 molecules of oxygen gas O2 are equivalent to approx. 0,6 moles.
How many moles of oxygen gas react with 0.100 mol of pentane C5H12?
The answer is 0,8 moles oxygen.
How many grams are in 6.5 moles of oxygen gas?
6,5 moles oxygen equals 208 g.
What does 2O 2 represent?
2O2 in a chemical reaction equation means that there are two moles of O2, or oxygen, molecules.
