Answer :
Molarity is given by the following equation:
[tex]M=\frac{mol}{liters}[/tex]From this equation, we can solve for liters and use the given values:
[tex]liters=\frac{mol}{M}[/tex]Replace for the given values:
1. 0.902M
[tex]liters=\frac{0.275mol}{0.902M}=0.305lt[/tex]2. 1.61M
[tex]liters=\frac{0.275mol}{1.61M}=0.171lt[/tex]
