Answer:
Explanations:
The formula for calculating the density of a substance will be used to get the required mass:
Given the following parameters;
Convert gallons to mL using the conversion rate.
Substitute the given parameters into the formula as shown:
Convert the mass in grams to kilograms
Recall that 1000g = 1kg
Hence the required mass in kg that is in 2642 gal. of a solution whose density you experimentally determined to be 0.736 g/mL is 7360.775kg
