0.38 g sample of NaNO3 is dissolved in ...

0.38 g sample of `NaNO_3` is dissolved in 250 ml flask. The molarity of the solution is

A

0.018 M

B

0.095 M

C

0.260 M

D

0.016 M

Text Solution

Verified by Experts

The correct Answer is:
A
Moles of `NaNO_3 = (0.38)/(85)`
Molarity` = ( (0.38)/(85) xx 1000)/(250) = 0.018 M `
