How many moles of MgCl2 are present in 47.5 mL of 0.260 M MgCl2 solution?

0.01235 moles

Explanation:

Given data:

volume = 47.5 ml = 0.0475 L

concentration = 0.260 M

To  find:

number of  moles: ?

Formula:

No of moles = concentration x volume (in litres)

M is equal to moles per liter, so if you multiply the volume in liters times the value of M, the result will tell you the number of moles.  

Solution:

no. of moles = 0.260 M x 0.0475 L

= 0.01235 moles
