Question

Calculate the percent mass per volume, % (m/v), of a dextrose solution containing 6.00 g of dextrose in 2.50×102 mL of solution. Note that mass is not technically the same as weight, but the abbreviation % (w/v) is often used interchangeably with % (m/v).

Answer 1

The percent mass per volume of the solution = 2.4%

Step-by-step explanation

Given that:

Mass of dextrose in the solution = 6.00 g

Volume of solution = 2.50 x 10² mL

What to find:

To calculate the percent mass per volume of the solution.

Step-by-step solution:

To calculate the percent mass per volume of the solution, we use:

`Percent\text{ }mass\text{ }per\text{ }volume=\frac{Mass\text{ }of\text{ }solute}{Volume\text{ }of\text{ }solution}*100`

Substitute the parameters given into the formula, the % (m/v) is

`Percent\text{ }mass\text{ }per\text{ }volume=(6.00)/(2.50*10^2)*100=2.4\%`

The percent mass per volume, % (m/v) of the solution is 2.4%.
