To calculate the mass of water, we can use the formula:
Mass = Density x Volume
Given that the density of water is 1 gm/cm³ and the volume is 100 m³, we need to convert the volume from cubic meters to cubic centimeters since the density is given in grams per cubic centimeter.
1 m³ = 1,000,000 cm³ (since 1 meter = 100 centimeters)
So, 100 m³ = 100,000,000 cm³
Now we can calculate the mass:
Mass = Density x Volume = 1 gm/cm³ x 100,000,000 cm³ = 100,000,000 gm
Therefore, the mass of 100 cubic meters (m³) of water is 100,000,000 grams.
