Given: Solution:
m (solution) = 150g + 30g 1. Let’s calculate the mass of sugar in the resulting solution.
w (sugar) = 0.2 m (sugar) = m (solution) * w (sugar) +30 g = 150 * 0.2 + 30 = 60g
m (sugar) = x + 30 2. Find w sugar in the resulting solution.
w (sugar) = m (sugar) / m (solution) = 60/180 = 0.3333
w (sugar) -? or 33.33%
m (sugar) -? Answer: w (sugar) = 33.33%
