Question

A solution contains 35 mL of 1.50M CuSO​ . What is the molarity when the new 4​ volume is 100mL

Answer 1

Answer:

0.525 M CuSO

Explanation:

Molarity (M) is the units mol/L. Let's figure out how many moles of CuSO we have:

35 mL = 35/1000 L = 0.035 L

0.035 L * 1.50 mol/L = 0.0525 mol CuSO

Our new volume is 100 mL, so let's first convert this to L:

100 mL = 100/1000 L = 0.100 L

To find the new molarity, divide the number of moles (0.0525 moles) by the number of liters (0.100 L):

0.0525 mol / 0.100 L = 0.525 M CuSO

Hope this helps!
