Answer:
0.60 M
Explanation:
Given data:
Mass of MgS = 32.9 g
Volume of solution = 971 mL (0.971 L)
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Number of moles of MgS:
Number of moles = mass/molar mass
Number of moles = 32.9 g/ 56.38 g/mol
Number of moles = 0.58 mol
Molarity of solution:
M = 0.58 mol/ 0.971L
M = 0.60 M
