density of a sample of zinc that has a mass of 48 kilograms and a volume of 7.5 mL.
To determine the density of a substance, you need to know its mass and volume. The formula to calculate density is:
Density = mass / volume
Given that the mass of the zinc sample is 48 kilograms and the volume is 7.5 mL, we can now substitute these values into the formula:
Density = 48 kilograms / 7.5 mL
To calculate the density, we need to convert the volume from milliliters to liters, as the mass is given in kilograms. There are 1000 milliliters in a liter:
Density = 48 kilograms / (7.5 mL / 1000 mL/L)
Simplifying, we obtain:
Density = 48 kilograms / 0.0075 liters
Now, divide the mass by the volume to find the density:
Density = 48 kilograms / 0.0075 liters
