2g of hydrogen combine with 16g of oxygen to form water.How many grams of water will be formed?Please help me solve this problem as soon as possible!
The balanced equation for the reaction is:
2H2 + O2 → 2 H2O
This shows two moles of Hydrogen reacts with 1 mole of oxygen in order to produce 2 mole of water.
Mass of 1 hydrogen = 1 g per mole
Mass of 1 oxygen atom = 16 g per mole
Mass of 1 water molecule is 18 g per mole
Hence 4 g of hydrogen reacts with 32 g of oxygen to produce 36 g of water
On dividing the above equation by 2, we will get
2 g of hydrogen reacts with 16g of oxygen in order to yield 18 g of water.
