Question

What is the mass percent of an unknown solution when 270 grams of solute are combined with 460 grams of water?

Answer 1

In order to find the percent mass composition of a solute in a solution, we must use the following formula:

%mass = mass of solute/mass of solution

Now, we know that:

mass of solute = 270 grams

mass of solution = 460 grams

Adding these values into the formula will give us:

%mass = 270/460

%mass = 0.5869

Therefore the percent mass composition is 58.7 =%i
