If the density of water is 1 g/ml, what is the mass of 3ml of water?<br><br> PLEASE HELP
SCORPION-xisa [38]

You can use dimensional analysis to figure this out.

=3\ ml × \frac{1g}{ml}

= 3 grams

If done correctly, ml and ml will cancel out, leaving you with grams.

If you don't know dimensional analysis, simply multiply <em>3 ml</em> by <em>1 grams </em>and that should still get you 3 grams.
