10 g of hydrogen and 64 g of oxygen were filled in a steel vessel and exploded. Amount of water produced in this reaction will be:

Options

A. 2 moles
B. 3 moles
C. 4 moles
D. 1 moles

Answer

C

Explanation

`{:(H_(2),+,(1)/(2)O_(2),to,H_(2)O),(1 " mol",,(1)/(2)" mol",,1 " mol"),((10)/(2) "mol",,(64)/(32)"mol",,?),(5 " mol",,2 " mol",,):}` `:'(1)/(2)` mole of `O_(2)` gives =1 mole of `H_(2)O`
`:.` 2 moles of `O_(2)` will give `=1xx2xx2`
=4 moles of water
