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]

Answer»

4.9 GRAM
19.6 gram
9.8 gram
0.98 gram

Solution :`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`
