Question

Find the amount of solute present in 240 g of
solution when its concentration is 12% (w/w).​

Answer 1

Answer:

Find the mass of the solute mixed in with the solvent. The solute is the substance that you’re mixing in to form your solution. If you’re given the mass of the solute in your problem, write it down and be sure to label it with the correct units. If you need to find the mass of the solute, then weigh it on a lab scale and record the measurement.

If the solute you’re using is a liquid, then you can also calculate the mass using the density formula, where density D = m/V, where m is the mass of the liquid and V is the volume. To find the mass, multiply the density of the liquid by the volume.

Tip: If you need to use a scale, subtract the mass of the container you’re using to hold the solute or else your calculations will be off.
