Question

Consider the following balanced equation: 2 H2 + O2 → 2 H2O
What mass of water (H2O) will be collected if 20.0 grams of oxygen gas (O2) are consumed?

(Mass of H2O = 18.02 g/mol and Mass of O2 = 32.00 g/mol)

Consider the following balanced equation: 2 H2 + 02 – 2 H20 What mass of water (H,0) will be collected if 20.0 grams of oxygen gas (0,) are consumed? (Mass of H20 = 18.02 g/mol and Mass of O2 = 32.00 g/mol) O a 11.31 grams of H,0 22.52 grams of H20 45.00 grams of H,0 90.10 grams of H,0

Expert Solution
Step 1

From the given data,it is clear that

2 mol H2 +1 mol O2 → 2mol H2O

we know that ,1 mol of  a compound = molar mass of that compound

molar mass of O2 = 32 g/mol

Then, 1 mol of O2 contains 32 g of O2

Also,molar mass of H2O= 18.02 g/mol

Then, 1 mol of H2O contains 18.02 g of H2O

:. 2 mol of H2O contains  2 X 18.02 g of H2O
