How to Calculate mass if density and volume are given?

Submitted by oneupj on Tue, 09/15/2009 - 18:03

I need help trying to figure out this problem on mass. Ok. Here is the problem. I need to calculate the mass of each object given. Gold-density=19.3 g/cm cubed, Sand-denisty=3.00g/cm cubed, and the volume is the same for each object- 1.75 L. What is confusing me is the g/cm cubed and L. Am I supposed to convert liters to grams and how to set up the problem would help me out. I appreciate any help because I sure need it right now. Thanks


Just use the numbers and multiply density x mass... that is the basic formula..the answer will still be in cm(3)


sorry you do need to convert the liters to millileters...multiply by 1000....1 mL = 1 cm(3)


sorry man i am almost asleep forgive me that's 1.75 / 1ooo to convert to milliliters

date=1253071149]First multiply liter by 1000 then multiply that to density?[quote author=absaluteviktory5 link=topic=4831.msg14868#msg14868
