calculate the molarity of each of the following solutions. use the periodic table if necessary. a salt solution with a volume of 250 ml that contains 0.70 mol nacl. m done

Answer

Explanation:

Step1: Convert volume to liters

The volume is given as 250 mL. Since 1 L = 1000 mL, we convert the volume $V$ to liters. $V=250\ mL\times\frac{1\ L}{1000\ mL}=0.25\ L$

Step2: Use the molarity formula

The molarity formula is $M = \frac{n}{V}$, where $n$ is the number of moles and $V$ is the volume in liters. Here, $n = 0.70\ mol$ and $V=0.25\ L$. $M=\frac{0.70\ mol}{0.25\ L}=2.8\ mol/L$

Answer:

$2.8$
