ANSWER:Problem 6SAQ
A sodium nitrate solution is 12.5% NaNO3 by mass and has a density of 1.02 g/mL. Calculate the molarity of the solution.
a) 1.44 M
b) 12.8 M
c) 6.67 M
d) 1.50 M
Step by Step Solution
Step 1 of 2
From the given,
Mass percentage of = 12.5 %
Density of = 1.02 g/ml
Molar mass of = 1.02 g/ml
Let’s convert the given mass into moles.
Hence, the number of moles of solution is 0.147 mol.
Let’s calculate the density milliliter into liters.
Hence, the volume of the solution is 0.098 L.
