Answer:
0.213M
Explanation:
Given parameters:
Mass of sodium chloride = 5.9g
Volume of solution = 473mL = 0.473L
Unknown:
Molarity of solution = ?
Solution:
Molarity is one of the ways of expressing concentration.
It is defined as the number of moles of solute in a given solution;
mathematically;
Molarity = [tex]\frac{number of moles }{volume}[/tex]
Number of moles of NaCl;
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
molar mass of NaCl = 23 + 35.5 = 58.5g/mol
Number of moles = [tex]\frac{5.9}{58.5}[/tex] = 0.1moles
Molarity = [tex]\frac{0.1}{0.473}[/tex] = 0.213M
