Problem 108P
A solution is made using 88.4 g of and diluting to a total solution volume of 1.50 L. Calculate the molarity and mass percent of the solution. (Assume a density of 1.05 g/mL for the solution.)
Step by Step Solution
Step 1 of 3
Moles of can be calculated by the following formula.
.............(1)
From the given,
Mass = 83.4 g
Molar mass = 101.103 g/mol
Substitute the values in the equation (1)
Hence, 0.825 mol of is present in the 1.5 L.
