2. the density of a liquid is 8.03 x 10-1 kilogram per liter. what is the
mass (in kg) of liquid in a full 100,000 liter tank?

m = 80300 kg

Step-by-step explanation:

Data

m = ?

V = 100 000 l

d = 8.03 x 10⁻¹

Formula

d = m/V

clear m from the equation

m = dV

substitute values

m = 8.03 x 10⁻¹ x 100 000 = 80300 kg

answer: 8 years

step-by-step explanation:

the explanation is that in 8 years the child will be 20 and in 8 years the father will be 40 and 20 is half of 40.
