Expert Answer

Step 1

The density of solution is assumed as 1.01 g/ml. Assuming a volume of 1000 ml, the mass of solution is calculated as,

Step 2

Now, the solution contains 1.44 % of formic acid by mass in the solution, hence, the mass of formic acid in the solution can be calculated as,

0.0144 x 1010 = 14.54 g of formic acid.

Now let us calculate the number of moles in 14.54 g of formic acid, which can be calculated as,
