How many grams of hydrogen are needed to produce 1.80g of water according to this equation?
2h2+o2 to 2h2o

0.2g of hydrogen is needed to produce 1.80g of water

Explanation:

No. of moles of water

From given values,

Weight of water

Molecular weight of water

No. of moles of water

From equation, it is clear that 2 moles of water can be formed by 2 moles of

Hence, 0.1 mole of water can be formed from 0.1 mole of

Now,

No. of moles of
