The density of water is 1 g/cm^3. What is the mass of 7.500 liters of water reported in kilograms?

I got 7.5kg. Is this correct?

in 7.500 liters, there are 7500 cm^2, and 7500 grams is 7.5kg

so is my answer correct?

Hmmmm. Did you read my answer?

yes

To find the mass of 7.500 liters of water in kilograms, we need to first convert liters to cubic centimeters (cm^3), since the density of water is given in units of grams per cubic centimeter (g/cm^3).

We know that 1 liter is equal to 1000 cubic centimeters (cm^3). Therefore, to convert 7.500 liters to cm^3, we multiply by 1000:

7.500 liters * 1000 cm^3/liter = 7500 cm^3

Now that we have the volume in cm^3, we can calculate the mass by multiplying the volume by the density. The density of water is given as 1 g/cm^3, so:

mass = volume * density
mass = 7500 cm^3 * 1 g/cm^3 = 7500 g

Finally, we can convert the mass from grams to kilograms. Since 1 kilogram is equal to 1000 grams, we divide the mass in grams by 1000:

mass = 7500 g / 1000 = 7.5 kg

So, your answer of 7.5 kg is indeed correct. The mass of 7.500 liters of water is 7.5 kilograms.
