Calculate the mass of copper hydroxide (2), which is formed when copper chloride (2)

Calculate the mass of copper hydroxide (2), which is formed when copper chloride (2) merges the amount of 0.5 mol with barium hydroxide?

To solve the problem, we compose the equation:
Y = 0.5 mol X g -?
1. CuCl2 + Ba (OH) 2 = Cu (OH) 2 + BaCl2 – ion exchange reaction, a copper hydroxide precipitate was obtained;
2. Calculation by formulas:
M Cu (OH) 2 = 97.5 g / mol;
Y Cu (OH) 2 = 0.5 mol since the amount of these substances according to the equation is 1 mol.
3. Find the mass of the product:
m Cu (OH) 2 = Y * M = 0.5 * 97.5 = 48.75 g.
Answer: in the process of ion exchange, copper hydroxide with a mass of 48.75 g was formed.
