Question 179468: A graduated cylinder contains 21.0 of water. What is the new water level after 30.0 of silver metal with a density of 10.5 is submerged in the water?
I used the formula d=m/v but my answer comes out to 21.35ml and the program says this is wrong. I am not sure if i am doing it wrong or have the wrong # of sig figs.

You can put this solution on YOUR website!
guessing that the units are grams and milliliters/cubic centimeters
ml and cm^3 are equivalent

if the density of the metal is 10.5g/cm^3,
then 30.0g has a volume of 30.0/10.5 or 2.86cm^3

this, added to the original 21.0ml, gives 23.9ml
