Calculate the mass of a liquid with a density of 3 g/mL and a volume of 20 mL.

Given that,

Density of the liquid, d = 3 g/ml

Volume, V = 20 mL

To find,

The mass of the liquid.

Solution,

The density of an object is given by its mass divided by volume such that,

d = m/V

m is mass

m = d×V

Put all the values,

m = 3 g/mL × 20 mL

= 60 grams

Hence, the mass of a liquid is 60 grams.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
