How many grams of precipitate is formed when 160 grams of copper sulfate 2 interacts with potassium hydroxide?

| To solve, we write down data on the condition of the problem:
m = 160 g X g -?
CuSO4 + 2KOH = Cu (OH) 2 + K2SO4 – ion exchange, copper hydroxide is released in the sediment.
We make calculations using the formulas:
M (CuSO4) = 159.5 g / mol;
M Cu (OH) 2 = 97.5 g / mol;
Y (CuSO4) = m / M = 160 / 159.5 = 1 mol;
Y Cu (OH) 2 = 1 mol since the amount of substances is 1 mol.
3. Find the mass of the sediment:
m Cu (OH) 2 = Y * M = 1 * 97.5 = 97.5 g
Answer: the mass of copper hydroxide is 97.5 g
