The `[H_(3)O^(+)]` concentration in the 200 mL. `H_(2)SO_(4)` solution is 1 M. How much `H_(2)SO_(4)` is dissolved in the solution ? [H = 1, O = 16, S = 32 gram/mole]

Options

A. 4.9 gram
B. 19.6 gram
C. 9.8 gram
D. 0.98 gram

Answer

C

Explanation

`H_(2)SO_(4)to2H^(+)+SO_(4)^(-2)`
`2xx x=1`
`x=0.5 M`
`therefore 0.5 = (x xx1000)/(98xx200)`
`therefore x = 9.8 g`
