Homework help! Density problems?

Please help with science homework (I am bad at science. This is DENSITY problems. Thanks
Question Details: I have a density worksheet and some of the problems i cannot find the answer.

Thank you for your help in advance, and I appreciate what you are doing for me.

Q. Calculate the density of a liquid in a beaker when the empty beaker has a mass of 15.25 grams. The beaker plus the unknown liquid has a mass of 49.5 grams and the miniscus is read at 11.6 cm3.

Q. (not 100 percent sure on this one) Cac12 is used as a de-icer in the winter. It has a density of 2.50 g/cm3. What is the mass of 12040 cm3 or ml?

Thanks!!
