Question

What is the mass of sodium chloride used to create a 100 mL solution at a concentration of 1.5 M?

Answer 1

The mass of sodium chloride required to make a 100 mL solution at a concentration of 1.5 M is 8.766 g.

Step-by-step explanation:

To calculate the mass of sodium chloride required to make a 100 mL solution at a concentration of 1.5 M, we need to use the formula:

mass = concentration x volume x molar mass

First, we convert the volume from milliliters to liters: 100 mL = 0.1 L

Next, we substitute the given values into the formula: mass = 1.5 M x 0.1 L x molar mass of sodium chloride

The molar mass of sodium chloride (NaCl) is 58.44 g/mol, so we can calculate the mass:

mass = 1.5 M x 0.1 L x 58.44 g/mol = 8.766 g
