An unknown liquid has a density of 1.23g/ml. what mass of the unknown liquid in grams will occupy a volume of 31.2ml

Answer is 38.38 g

Explanation;

To find out the mass, we can apply the simple formula,

d = m / v

Where, d is the density of the substance, m is the mass and v is the volume of the substance.

Values of d and v are given as follows;

d = 1.23 g/mL

v = 31.2 mL

m = ?

By applying the formula,

1.23 g/mL = m / 31.2 mL

            m = 1.23 g/mL x 31.2 mL

            m = 38.376 g = 38.38 g

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

c. 75.7

i think that is the right
