Calculate the active mass of 10 g hydrogen in a 10 - L vessel.

Text Solution

Verified by Experts

10 L vessel contains 10 g of `H_(2)`
`therefore 1L` vessel contains `(10)/(10)` g of `H_(2)`
2 g of `H_(2) = 1 mol`
`therefore 1 ` of `H_(2) = (1)/(2) = 0.5 mol L^(-1)`
or
Molar concentration
` = ("Mass")/("Gram molecular mass") xx (1)/("volume in " dm^(3))`
` = (10)/(2) xx (1)/(10) = 0.5 mol L^(-1)`
