Calculate the moles of H(2)O vapours for...

Calculate the moles of `H_(2)O` vapours formed if `1.57` mole of `O_(2)` are used in presence of excess of `H_(2)` for the given change,
`2H_(2)-O_(2)rarr2H_(2)O`

Text Solution

Verified by Experts

`:' 2 "mole" H_(2)~= 1"mole"O_(2)~=2"mole"H_(2)O`
`:' 1 "mole" O_(2)~=2"mole"H_(2)O`,
`:. 1.57"mole"O_(2)~=2xx1.57"mole"H_(2)O`
`= 3.14 "mole"H_(2)O`
or, Moles of `H_(2)O= [1.57 "mole of" O_(2)][(2 "mole"H_(2)O)/(1 "mole"O_(2))]`
`= 1. 57xx(2)/(1)= 3.14 "mole"`
