How many moles of 4.25 mL of .105 M CaCl2 solution have

There are 4,46x10e-4 moles of  CaCl2 (0,000446 mol)

Explanation:

A molar solution indicates the amount of moles of solute (in this case CaCl2) in 1 liter of solution (1000ml).

1000ml 0,105 mol CaCl2

4, 25 mlx=(4,25 ml x0,105 mol CaCl2)/1000ml= 4,46x10e-4 mol CaCl2
