Thread: help with percentages????

Hi i need a little help working something out i need to figure out 10% of 1000ml but the 10% needs to be in grams. I have confused myself so thought i would ask for some help!!!! So if some one could explain it to me that would be great! thank you so much!!!! x

Grams measure mass; liters measure volume. So you'll need the density information in order to convert from milliliters to grams. Only then can you find ten percent.

10% of 1000 = 1000 * .10 = 100ml

Now you're stuck!! Milligrams?

10% of 1000 ml is 100 ml, of course. Now one ml of water (at standard temperature and pressure) has a mass of 1 gram. Is that what you are talking about?

As others have told you "ml" and "grams" measure different kinds of things. It is only the special case of water that they can be equated. For other things, it depends on the density.

First solve what is 10% of 1000ml <equal to 100ml>. Now considering the liquid to be water which has a density of 1gram/ml then your answer would be 100 grams. Thus 100ml is equal to 100 grams.

Here is a link to the conversion from volume to weight.

Hope this solution satisfies you.
