Question

What is the mass in grams of 1.00 gallon of water? The density of water is 1.00 g/mL.

Answer 1

hint: \[\text{mass = density} \times \text{volume}\]
does that help?

Answer 2

so what's the mass and volume?
lol im stupid

Answer 3

first, turn gallons into mL

Answer 4

according to this http://www.google.com/search?q=1+gallon+%3D+%3F+mL&sugexp=chrome,mod=8&sourceid=chrome&ie=UTF-8

1 gallon = 3,785 mL

Answer 5

so

mass = 1 g/mL x 3,785 mL

what do you think is the answer then?

Answer 6

btw... density is the one in g/mL and volume is the one in mL

Answer 7

so the mass is 3785

Answer 8

yes.

Answer 9

dont forget the units... 3785 g

Answer 10

okay. soo 3785 = density x volume.. so whats the density and volume again

Answer 11

density is that 1 g/mL and volume is 3785 mL

just remember... if you see g/mL <--that's density

if you see mL <--that's volume

Answer 12

thankkyou! :) got it..

Answer 13

welcome
