Answer:
Molarity = 0.74 M
Explanation:
Given data:
Molar concentration of solution = ?
Mass of NaCl = 37.1 g
Volume of water = 0.850 L
Molar mass of NaCl = 58.44 g/mol
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 NaCl:
Number of moles = mass/ molar mass
Number of moles = 37.1 g /58.44 g/mol
Number of moles = 0.63 mol
Molarity = 0.63 mol / 0.850 L
Molarity = 0.74 M
