Answer: 1.23 M Ca

Explanation:

Molarity is moles of solute/volume (only liters) of solution

Convert mL to L

To do that divide by 1000

Therefore, 2.34 mol/1.86 L

Answer is 1.23 M Ca

Answer:

1.258 M

Explanation:

Molarity = [tex]\frac{Moles of solute}\\{Volume of the solution in L}[/tex]

Given.

Moles of Calcium = 2.34 mol

Volume of the solution = 1860 ml

1 L = 1000 ml

1860 ml x [tex]\frac{1L}{1000 ml}[/tex] = 1.86 L

Molarity = [tex]\frac{2.34 mol}{1.86 L}[/tex] = 1.258 M
