A particular brand of gasoline has a density of 0.737 g/mL at 25 degreesC, How many grams of this gasoline would fit in a 14.8 gal tank. Please help me solve this!

They're US gallons

1 gal = 3.79 L = 3790ml
so there are 3790ml/gal
then
V = 14.8gal = 14.8gal * 3790ml/gal = 56092 ml
and given d = 0.737g/ml
so
m = dV = 0.737g/ml * 56092ml = 41300g
rounded to 3 sig figs
the important thing is to take notice to the units
You need to ask yourself how can I combine
gal, ml/gal and g/ml to get the answer in g
treat the units like fractions
gal * ml/gal * g/ml = g
.

1 gal = 3785.4118 mL
Figure out how many mLs are in 14.8 gallons.
Then multiply the mLs by the density to get your weight.
I don't want to hand you the answer, since I assume it is for school, but work through the problem using the hints I gave you and you should get the correct answer. Good luck.

Given a 14.8 gal tank, start there. Then multiply by values of (1) to convert the units to grams.
1 gal is now defined as 3.785411784 L
14.8 gal (3.785411784 L/gal)(1000ml/L)(0.737gm/ml)
= 41,289.7575751584 grams
Now adjust to 3 sigfigs due to 14.8 having 3 digits:
41,300 grams

I somewhat have this subject for gaining knowledge of chemistry and that i've got been given it suitable: remember: a million gallon= 3.78L changing gallon to mL sixteen gallon x (3.78L/a million gallon) x (1mL/10^-3 L) = 60480 mL gallons cancel, liters cancel..enable with mL d=m/v fixing for mass (grams) 0.737=mass/60480 mass=44573.seventy six want 2 sig figs requesting grams so answer is= 4.5x10^4

Simply convert 14.8 gal to ml, then divide by the density to get the answer in grams
.
(I'm assuming it's US dry gallons)
Therefore, mass
= 65192.279808728 / 0.737
= 88456.281965709633649932157394844
= 88500 g (3 significant figures)
