A2.0% (m/v) nacl solution contains g nacl in 300. ml of solution.

300 mL of NaCl solution contains NaCl.

Further Explanation:

The concentration is the proportion of substance in the mixture. The most commonly used concentration terms are as follows:

1. Molarity (M)

2. Molality (m)

3. Mole fraction (X)

4. Parts per million (ppm)

5. Mass percent ((w/w)%)

6. Volume percent ((v/v)%)

7. Mass per volume percent ((w/v)%)

Mass per volume percent is defined as the amount of solute dissolved in a given volume of the solvent, multiplied by 100 %.

The formula to calculate the mass per volume percent of the solution is as follows:

Given information:

A 2.0 % (m/v) NaCl solution

To calculate:

Amount of NaCl in 300 mL of the solution

Firstly, we have to find out the amount of NaCl that is present in 2.0 % NaCl solution.

A 2.0 % NaCl solution indicates that 2 g of NaCl is dissolved in 100 mL of the solution.

So the amount of NaCl in 300 mL of the solution is calculated as follows:

So 300 mL of NaCl solution contains 6 g of NaCl.
