Your family is going to have a contractor build a pool in your backyard. Your mom wants to make this a learning experience, so she asks you to find the mass of the water that will fill the pool. She has told you that the pool holds 75,700 L of water, and you know that the density of water is 1,000 g/L. Use the equation D = m/V to determine the mass of the water in grams.
757,000 g
7,570 g
75,700,000 g
757 g
If 757 g is your answer I don't agree. On second thought that looks like another choice for an answer. I don't understand your problem. If D = M/V then
mass = volume x density. Just plug and chug.

Use the formula, that will help you out.
To determine the mass of the water, we can use the equation D = m/V, where D represents the density, m represents the mass, and V represents the volume.
Given that the density of water is 1,000 g/L, and the volume of water the pool holds is 75,700 L, we can substitute these values into the equation to solve for the mass.
D = m/V becomes 1,000 g/L = m/75,700 L.
To isolate m, we can cross-multiply and divide:
1,000 g/L * 75,700 L = m.
This gives us a mass of 75,700,000 grams. Therefore, the correct answer is 75,700,000 g.
