What volume of solution gives the desired moles?

0.53mol from a 7.25M solution

0.035mol from a 1.25M solution

0.0013mol from a 0.090M solution

1. 0.073L

2. 0.028L

3. 0.014L

Explanation:

The volume for the different solutions are obtained as shown below:

1. Mole = 0.53mol

Molarity = 7.25M

Volume = ?

Molarity = mole / Volume

Volume = mole / Molarity

Volume = 0.53/7.25

Volume = 0.073L

2. 0.035mol from a 1.25M

Mole = 0. 035mol

Molarity = 1.25M

Volume = ?

Molarity = mole / Volume

Volume = mole / Molarity

Volume = 0.035/1.25

Volume = 0.028L

3. Mole = 0.0013mol

Molarity = 0.090M

Volume = ?

Molarity = mole / Volume

Volume = mole / Molarity

Volume = 0.0013/0.090

Volume = 0.014L
