Question

Calculate the molarity of 7.6 mol MgCl₂ in 527.3 mL of solution.O a. 0.0144O b. 1.44e-5O c. 6.94e4O d. 14.4

Answer 1

Step-by-step explanation:

To solve this question, we need to use the following formula:

M = n/V

where:

n = number of moles = 7.6

V = volume of the solution = 527.3 mL = 0.5273 L (you need to divide mL to 1000 to find the value in L)

so:

M = 7.6/0.5273

M = 14.4 mol/L

Answer: d. 14.4
