What is the weight (in g) of Na(2) CO(3)...

What is the weight (in g) of `Na_(2) CO_(3)` (molar mass= 106) present in 250 mL of its 0.2 M solution?

A

1.06

B

53

C

5.3

D

10.6

Text Solution

Verified by Experts

The correct Answer is:
( c)
Mwt of `Na_(2)CO_(3)=106`
Volume of solution =` 250ml`
Molarity `=0.2M`
Weight of `Na_(2)C0_(3)`
=` (" Molarity"xx "Mwt"xx" Volume of solution")/(1000)("in " ml)`
`(0.2xx106xx250)/(1000)`
= `5.3g`
