1) Determine the total weight of the resulting solution.
To do this, add the indicated weight of sugar to the known mass of water.
Will be:
180 + 20 = 200 grams.
2) Find the mass fraction of sugar in the resulting solution.
To do this, divide 20 grams of sugar by the total weight of the solution and multiply by 100%.
Thus, we get:
20/200 * 100% = 2000/200 = 10%.
Answer: The proportion of sugar in the solution is 10%.
