The dry weight of a sample is 330 g, and its weight when saturated with water is 360 g. The apparent weight of this sample in water is recorded as 225 g. Given that the density of water is 1g/cm3, find the porosity of the sample. Assuming the sample is coated with a material of negligible weight. Is the porosity effective or total?

Weight-Volume relationships

Weight is defined as the quantity of matter contained in a body. Weight can also be defined as the force acting on a body due to gravity. Mathematically, weight can be defined as-
