Guess What?? IT'S DENSITY TIMEE!!!!

Ready for some Density? OKay! 

First of all, the formula for density is.. Density =Mass

                                                                  volume

Other ways to write the formula are...

V = m       or       m = DV

       D

REMEMBER:
solid is g/cm3
liquid is g/mL
1 cm3 of water = 1mL

Density of water is 1000 g/L or 1.0 g/mL

If the d objeect < dliquid then it's floating

If the dobject is >dliquid then it's sinking

Here's an example question! 

In a balloon, helium occupies 3.5 L with a mass of 4.0 g. What is the density?

Ans: D = m/v = 4.0/3.5 = 1.1g/L

Now that you've done all these density things, it's time for something fun! Try this if you want!
