What do you put in the water?

If the water is spiked, I believe it will weight a bit more than that. Also depends on where you weigh it. If you ask my local butcher to weigh it, 250ml will equal to 300grams (or more) using his scale because everytime I buy a chicken that looks no more than 750gram, it always weigh 1kg under his scale.

Wait, really? So the red marks on my English papers don't point out examples of my superior writing ability?

On the moon, at NIST STP it will weigh about 41.6665 gram,
while at earths equator under the same circumstances it will be about 248.83134 gram.

This assuming we're dealing with pure H2O, no salts, gases or other stuff dissolved in it.

What is 250mL of water in kg?



Find out for yourself, measure out the 250ml, weigh it and record your answers including the margins for error at each stage of the process. It might get you credit and at the least you'll have your own research to back it up

Dude.. that would involve blood, sweat and tears for Gen Z! You have no idea how troublesome that is!

Apparently, I'm Generation Y. What generations are you all?

mass != weight.

I'm in between x and y. Maybe leading edge of y, or tailing edge of x.

Gawsh, it's 42.

Any other questions?

BTW, I'm from Generation Z and I have at least a 4.0 average, which probably doesn't say much considering it's much easier to do well now than before, according to some oldsters.

Oh, what if the water is in vapor form? Or solid?
