6g of sugar is dissolved in 250mL of water. What is the percent concentration of sugar in mass per unit volume?

$\small 2.4%$

$\small 0.024%$

$\small 6%$

$\small 60%$

Explanation

Concentration can be measured in a variety of ways. To find the percent mass per unit volume, we must divide the mass of solute by the volume of solvent and multiply by 100%.

$C=\frac{m}{V}\times 100%$

We know our mass is 6g and our volume is 250mL. Use these values in the equation to find the concentration.

$C=\frac{6g}{250mL}\times100%$

$C=0.024\times100%=2.4%$
