I have two problems to solve that I don't know how to do,I missed school last week and the teacher gave me the worksheet,but I couldn't get a copy of the notes that explained how to do it,haha.
1)A block of aluminum occupies a volume of 15.0 L and weighs 40.5 g.What is the density?
2) Mercury metal is poured into a graduated cylinder that holds exactly 22.5 mL.The mercury used to fill the cylinder weighs 306.0 g.From this information,calculate the density of mercury.
I know that density=mass/volume,but I don't know the relationship between volume,mass,and weight.Anyone care to give me a hand?

Ok, so before the big bang, there was no matter right? (if if there was where did it come from??) so if there was no matter, and no energy( and if there was...where did it come from??) so what exactly exploded? Gases?! where did they come from?? you get the idea....energy can't be created or destroyed right? but energy had to come from somewhere, so where?
and i've heard something about a 'singularity' if that theory is true..how did the singularity form? please, no angry bashing on evolutionists or creationists, i just want a straight answer. thanks!
