Question

how many grams in a mililiter?

Answer 1

1ml

Answer 2

depends upon density of subsance if water 1gm=1ml

Answer 3

It depends upon the density of the substance. For water, we say that 1mL = 1g, because water's density is so close to 1. There is no direct relation that works for EVERY substance, because each is different.

Example: If we have a 100g of a substance, X, whose density is 20 g/mL,

100g * 1mL / 20 g = 5mL.

But for water, 1mL approx. = 1 g
It varies from substance to substance, because their densities are not equal. If you know the liquid/substance, you can find its density. Then I can help you more.
