Step 1

It is required to calculate the number of grams of K2CrO4 in K2CrO4 solution and it says that the mass of K2CrO4 is 20% of the mass of the solution. First, we need to calculate the mass of 75 mL K2CrO4 solution having a density of 1.175 g/mL, which can be done as,

Step 2

Now since the mass of K2CrO4 is 20% of the mas...
