100 ml solution contains 12 mg MgSO_(4). The concentration of solution

1.	100 ml solution contains 12 mg MgSO_(4). The concentration of solution is
Answer» `10^(-3)M` `2XX10^(-3)N` 120 ppm `10^(-3)m` Solution :`M=(12xx10^(-3))/(120xx0.1)=10^(-3)M=2xx10^(-3)N` ppm `(w_(1))/(w_(2))xx10^(6)=(12xx10^(-3))/(100)xx10^(6)=120`ppm For dilute solution, m = M
