Copper sulphate solution reacts with sodium hydroxide solution to form a precipitate of copper hydroxide according to the equation :
`2NaOH +CuSO_(4) to Na_(2)SO_(4)+Cu(OH)_(2)darr`
What mass of copper hydroxide is precipitated by using 200 gm of sodium hydroxide ?
[H = 1,0 = 16, Na = 23, S = 32, Cu =64]

Explanation

To find the mass of copper hydroxide (Cu(OH)₂) precipitated by using 200 grams of sodium hydroxide (NaOH), we can follow these steps:

### Step 1: Write the balanced chemical equation
The balanced equation for the reaction is:
\[ 2 \text{NaOH} + \text{CuSO}_4 \rightarrow \text{Na}_2\text{SO}_4 + \text{Cu(OH)}_2 \]

### Step 2: Calculate the molar mass of sodium hydroxide (NaOH)
Using the atomic masses provided:
