What is the concentration of a 2500 milliliter solution that contains 7.5 moles of CaCO3? (Hint: there are 1000 milliliters (mL) in 1 liter (L) )

M = 3.0 M.

Explanation:

Hello there!

In this case, according to the definition of molarity, it turns out possible for us to calculate the required molar concentration of the given volume of solution and moles of solvent by knowing they are divided as follows:

However, since the volume is in liters, we first convert the 2500 mL to L and then calculate the resulting molarity as shown below:

Whereas M stands for molar units of mol/L.
