how many moles of solute are contained in 18.5ml 2.5m CaCL2
I worked this problem just below just a short time ago. The formula for obtaining mols hasn't changed since then.
mols = M x L = ?

To calculate the number of moles of solute, we need to use the formula:
moles = concentration (in M) × volume (in L)
Given:
- Concentration of CaCl2 = 2.5 M
- Volume = 18.5 mL
First, we need to convert the volume from milliliters (mL) to liters (L):
18.5 mL ÷ 1000 = 0.0185 L
Now, we can plug the values into the formula:
moles = 2.5 M × 0.0185 L
moles = 0.04625 mol
Therefore, there are 0.04625 moles of CaCl2 in 18.5 mL of a 2.5 M solution.
