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 102 cm3. 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 104 g
b) The volume of this substance is 9 x 102 cm3. 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 104 gb) The volume of this substance is 9 x 102
cm3. Given that Density = Mass ÷ Volume, find the density of this substance.Density = (3.6 x 104) ÷ (9 x 102)
= 0.4 x 102
= 4 x 101 = 40 g/cm3
