Finding mass of gasoline

Question

We know that the density of gasoline - 0.79g/mL

Help me find mass of gasoline (kg) in 25 a gallon tank?

 

 

Answer 1

(25gal)(3.785 L/gal) = 94.625L

 First of all, keep in mind that you will need to convert L info mL as our density is given in g/mL

1L = 1000 mL

(94.625L)(1000 mL/L) = 94,625mL

(94,625mL)(.79g/mL) = 74,753.75g

Now convert the mass 74,753.75g of gasoline into kg

(74,753.75g)(1kg/1000g)

= 74.75375kg

Mass gasoline ≅ 74.754 kg
