Question

What is the weight per volume of 50.0 mL NaCl solution that contains 2.94 g NaCl?

Answer 1

The weight per volume of the 50.0 mL NaCl solution with 2.94 g NaCl is 0.0588 g/mL, calculated by dividing the mass of the NaCl by the volume of the solution.

Step-by-step explanation:

To calculate the weight per volume of a 50.0 mL NaCl solution containing 2.94 g NaCl, we use the concept of concentration which is commonly expressed as mass per unit volume. In this case, we use the mass of the NaCl and divide it by the volume of the solution to obtain the weight per volume in grams per milliliter (g/mL).

The formula for weight per volume is:

Concentration (g/mL) = Mass of solute (g) / Volume of solution (mL)

Using the values provided:

Concentration = 2.94 g / 50.0 mL

Concentration = 0.0588 g/mL

So, the weight per volume of the NaCl solution is 0.0588 g/mL.
