Mass of the serving = 40 g
Mass % of sugar in the 40 g serving = 30 %
Mass of sugar in the 40 g serving = [tex] 40 g serving * \frac{30 g sugar}{100 g serving} = 12 g sugar [/tex]
10 g of sugar is added.
So the total mass of sugar added = 10 g + 12 g = 22 g
Total mass of the solution = 10 g solute (sugar) + 40 g (serving) = 50 g
Mass % of the resulting mixture = [tex] \frac{22 g}{50 g} * 100 = 44 % [/tex]
Mass % of sugar in the
