1. 0.125mole of silver is required

2. 55mL of NaCl will be required

Explanation:

1. Molarity = 0.5M

Volume = 0.250 L

Mole = ?

Molarity = mole / Volume

Mole = Molarity x Volume

Mole = 0.5 x 0.250

Mole = 0.125mole

Therefore, 0.125mole of silver is required

2. Molarity = 0.01M

Mole = 0.55mole

Volume = ?

Molarity = mole / Volume

Volume = mole / Molarity

Volume = 0.55/0.01

Volume = 55mL

Therefore, 55mL of NaCl will be required
