What is the mass, in kilograms, of 14.0 L of gasoline? (Assume that the density of gasoline is 0.680 g/cm^3).?

Question

I dont get this. How can centimeters be converted into liters? Is it a trick question? Please help!!

Answer 1

1 cm^3 = 1 mL

Let gasoline be called G

14.0LG x 0.680gG/1mLG x 1000mLG/1LG x 1kgG/1000gG = 9.52kg gasoline

Answer 2

The little ^ thingy means to the third power, or cubed, therefore cm^3 means cubic centimeters There are 1000 cm^3 in a liter, and a liter thus weighs 1000 cm^3 x 0.680 g/cm^3, or .68 kg, and 14 liters weighs 14 x 0.68 kg

Answer 3

thats a cubic centimeter, not just a centimeter. i think a cubic centimeter is the same thing as a mililiter. theres conversion tables availble in your book and you can google 'metric conversion' and find a ton. your density is 0.00068 kg per mililiter. multiply that by another thousand and you will have kilograms per liter then just mult by 14 to get your ans in kilograms,

Answer 4

You're not converting cm into Litres. It's cubic centimetres (cc) and, 1cc of pure water = 1gram. 1,000cc (1L) = 1,000g.

Therefore, 1.0L of pure water = 1,000g.
14.L of water = 14kg.
The Density of gasoline = 0.680g/cm³ (g/cc or g/mL)
= A Specific Gravity (S.G.) of 0.680. (provable if you wish).
Density of water x S.G. of Gasoline
= 1,000g/L x 0.680 = 680g/L
680g/L x 14L = 9,520g = 9.52kg gasoline.
