General Chemistry

Question #171872

Calculate the molarity of 20.5 g sodium chloride (NaCl) compound with molar mass of

58.44g/mole placed in 55.0 mL of total solution.

Expert's answer

Moles of NaCl = "\\frac{20.5}{58.44}=0.35moles"

"55.0mL = \\frac{55}{1000}=0.055 L"

Hence

"Molarity = \\frac{0.35}{0.055}=6.36M"
