If we add 20g of salt to 150g of water, what is the concentration by mass of the solution?

Sagot :

Answer:

11.76% by weight in salt

Explanation:

concentration = mass of solute / mass of solute + mass of solvent

mass of solute = 20 grams

mass of solvent = 150 grams

mass of solute + mass of solvent = 20g + 150g = 170g

concentration (weight %) =  (20g / 170g)100% = 11.76% by weight in salt.
