# What mass of caffeine is present in a 2.5*L volume of solution whose concentration was 1.00*mol*L^-1 with respect to caffeine?

Approx. $500 \cdot g$.................

#### Explanation:

We calculate the product...........

2.5*cancelLxx1.00*cancel(mol*L^-1)xx194.19* g*cancel(mol^-1)=??*g.

We have used the relationship:

$\text{Concentration"="Moles of solute"/"Volume of solution}$, and thus,

$\text{Moles of solute"="concentration"xx"volume of solution.......}$
