Question

3. How many moles of solute are present in a 2300 mL solution of 0.68 M MgSO.?​

Answer 1

There are 1.56 moles of solute present in a 2300 mL solution of 0.68M MgSO4.

How to calculate number of moles?

The number of moles of a substance can be calculated by using the following formula:

molarity = no. of moles / volume

According to this question, a volume of 2300 mL solution is contained in 0.68 M MgSO4. The number of moles is calculated as follows:

no of moles = 0.68M × 2.3

no. of moles = 1.56

Therefore, there are 1.56 moles of solute present in a 2300 mL solution of 0.68M MgSO4.
