Question

the density of aluminum is 2.70g/cm3 . express this value in units of kilogram per cubic metres

Answer 1

Answer:

2700kg/m∧3

Explanation:

1 gram = 10∧-3kg

2.7 gram = x

x= 2.7x10∧-3kg

1cm∧3 = 10∧-6m∧3

2.7g/cm∧3 = 2.7x10∧-3kg/10∧-6m∧3

                  = 2.7x10∧-3+6kg/m∧3

                  = 2.7x10∧3kg/m∧3

                  = 2700kg/m∧3
