Distances in our Universe The universe is so large that we must use special units of measurement. Kilometers and miles just won’t cut it.

Scientific notation is mathematical shorthand.

Exam Question This is (part of) a question from a Higher level paper at Grade A/B. a)The mass of a substance is 36000g. Write this in standard form. b) The volume of this substance is 9 x 10 2 cm 3. Given that Density = Mass ÷ Volume, find the density of this substance.

Exam Question a)The mass of a substance is 36000g. Write this in standard form. 3.6 x 10 4 g b)The volume of this substance is 9 x 10 2 cm 3. Given that Density = Mass ÷ Volume, find the density of this substance.

Exam Question a)The mass of a substance is 36000g. Write this in standard form. 3.6 x 10 4 g b)The volume of this substance is 9 x 10 2 cm 3. Given that Density = Mass ÷ Volume, find the density of this substance. Density = (3.6 x 10 4 ) ÷ (9 x 10 2 ) = 0.4 x 10 2 = 4 x 10 1 = 40 g/cm 3
