Question

What is the molarity of 2.34 mil of calcium in 1860 mL of solution?

Answer 1

Answer: 1.23 M Ca

Step-by-step 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 2

1.258 M

Step-by-step explanation:

Molarity =
`\frac{Moles of solute}\\{Volume of the solution in L}`

Given.

Moles of Calcium = 2.34 mol

Volume of the solution = 1860 ml

1 L = 1000 ml

1860 ml x
`(1L)/(1000 ml)` = 1.86 L

Molarity =
`(2.34 mol)/(1.86 L)` = 1.258 M
