How are 0.5 mol `Na_(2)CO_(3)` and 0.5(M) `Na_(2)CO_(3)` different?

Text Solution

Verified by Experts

Molar mass of `Na_(2)CO_(3)=(2xx23)+12+(3xx16)=106`
0.50 mol `Na_(2)CO_(3)=0.50xx106=53g` of `Na_(2)CO_(3)`
0.50 (M) `Na_(2)CO_(3)` means 53g of `Na_(2)CO_(3)` is present in 1L sodium carbonate solution.
