Problem: We dissolve 2.45 g of sugar in 200.0 g water. What is the mass percent of sugar in the solution? A) 1.21% B) 1.23% C) 2.42% D) 123% E) none of the above

FREE Expert Solution

We’re being asked to calculate the mass percent when 2.45 g sugar is dissolved in 200 g water.


We’re given the mass percent of the solution and we're going to use the mass percent formula shown below:

mass percent=mass componenttotal mass×100


Since we are dealing with a solution, we can rewrite the equation as:

% mass=mass solutemass solution×100
