Question

help please,fan and medal will be awarded to the best/helpful answer! :3
the density of a gasoline at room temperate is 0.70g/mL. if the gas tank of a car holds 12.0 gallons of gasoline, what is the mass of a full tank of gasoline? note that 1 gallon = 3.7854L

Answer 1

volume of tank = 12 * 3,7845
density = m/V
m = ?!

Answer 2

so since m = density x volume, do i just multiply (0.070g/mL) (12*3,7854L)?

Answer 3

check your units!!! are all units in g or kg, are all units in mL or L?

Answer 4

g/mL. L?

Answer 5

convert the volume to ml, that should be easiest way...

Answer 6

0.00007g/L

Answer 7

1 gallon = 3.7854L
12 gallons = 45.4248 L
density = 0,7 g/ml = 0,7 kg/L

density = m/V
m= density * V

Answer 8

oh wait. my bad loool, density should be 70g/L

Answer 9

ok then just recalculate it... but i gave you entire solution you just need to put in numbers and mind units...

Answer 10

thanks! i was having a hard time grasping the concept so i got my teacher to help me today :)
