Okay here is my situation, it's late at night and i've finally decided to do my homework
I measured out 100mL of water in a graduated cylinder but i don't know how to convert 100mL of water into grams. It's probably very easy but my brain isn't functioning correctly as usual :)
HELP!

1L of water is equal to 1Kg.
If you can't figure it out from there, may God help you.

EDIT - nevermind
Thinking about it now I'm not retarded
ok 100 grams easy conversion..

don't feel bad, I totally stared at this a while going, "eh what?"
100 mL= .01L
if ^^ is right, then
.01L=.01kg
.01kg=.01/1000gm=.00001gm
that doesn't seem right, as far as the numbers go, but if nippinout is right, then that's the conversion.

100mL = 0.1L

.01kg = 10g. You multiply by 1000, not divide.
EDIT: Since your first conversion was also incorrect I thought I'd throw in the correct answer -
100g
Just remember (snyper) that density measurements are derived from the density of water - therefore D for water = 1. When dealing with water or any other substance with D of 1, one mL = one g, one L = one kg. One of those things that's only easy if you know it.

Instant message smarterchild. He can do all kinds of conversions.

ok after rereading my homework i discovered that ... well it gave me the answer =)
100mL H2O = 100g H2O

Yeah, the gram is (basically) DEFINED as 1 mL of water.

1ml of water = 1g only at 4 degrees Celsius. It differs slightly as temperature diverges from 4 degrees. :dance:

Just to play devil's advocate here - why did you go on the internet and ask someone to literally do something for you?
Also, doing your homework late at night isn't the smartest thing to do...

atleast he is doing it
On my lab test today one of the questions was (3.43 * 10^3ml) * (2.45 * 10^4cm) figure that one out :)
He almost got me.

by using the density formula
density = mass/volume
density of H20 = 1 g/mL
