a flask that weighs 345.8 g is filled with 2.25 ml of carbon tetrachloride. the weight of the flask and carbon tetrachloride is found to be 703.55 g. from this information, calculate the density of the carbon tetrachloride. please help I just started chem and I suck at math

Question

Density is equal to mass over volume in formula is 
d=m/v
 In your case the mass (m) of the carbon tetrachloride will be the difference between the flask with the carbon tetrachloride (703.55g) and the weight of the flask alone (345.8g). You have to made this difference and that will be "m" in the density formula.  You have to divide this "m" by the volume "v" (2.25ml) and you will get the density of the carbon tetrachloride. 
If you need more help let me know.
