Answer to Question #71826 in General Chemistry for Kendra
Question #71826
There are 1000 liters in 1 cubic meter and 1000 grams in 1 kilogram. How many grams of air are in 1 liter of air? (Assume a density of 1.18 kg/m3.)
Expert's answer
Solution:
There are 1000 liters in 1 cubic meter, it means that volume and mass of 1 liter is 1/1000, or 0.001 of 1 cubic meter. Then:
Mass of 1 liter = 0.001*1,18=0.00118 kg
There are 1000 grams in 1 kilogram. It means that 1 kg = 1000 g, then:
Mass of 1 liter = 0.00118 kg*1000=1.18g
Answer: 1.18 g
