Find the number of automobiles whose total mass is the same as 1.0 mol blueberries.?

Question

The mass of an average blueberry is 0.75g and the mass of an automobile is 2200 kg.

Answer 1

1 mol = 6.022x10^23 blueberries
6.022x10^23 blueberriers x .75g/blueberry = 4.5165x10^23gm=4.5165x10^20kg/2200kg/car
this means that it would take 2.053x10^17 cars to equal 1 mol of blueberries

Answer 2

Use unit cancellation:

0.75 g/blueberry x NA (blueberries/mol blueberries) x (1 auto/2200 x 10^3 g)

= no. of autos per mol blueberries
