mytwoboysmom Jan 21, 2013 Any tips or ideas on how to work chem equations?Equations are not that hard, but look very confusing. The biggest thing to remember is write down what you start with, write down what you are trying to get. Make a plan to get there. (what do you need to do in order to end up with the unit of measure in the "what I am trying to get") Do the math. it is all just multiplying and dividing. take it one step at a time. 0 Likes

cnastriving2brn Jan 21, 2013 I'm having problems converting for example converting the mass of displaced water to volume if displaced water, assuming the density if water is 1 g/mL. 0 Likes

M-Roc Jan 21, 2013 I just finished my chemistry 101 class this past fall and I bought "Chemistry for Dummies" on Amazon. It broke down everything you need to know step by step. It helped me out so much! Good luck! 0 Likes

SmoothKeys Jan 21, 2013 The density formula is: P (rho) = mass/volume or P = m/vStep 1: the density of water is given and it is 1g/mlYou now have 1g/mL = m/vYou want to solve for volume and so you will have to rearrange the equationYou now have: vg/mL = m >>> vg = m (mL) >>>> volume = m (mL)/gram (note that grams is mass)So the equation is now: volume = mass (mL)/mass (grams notation will cancel)And you are now left with volume. So volume = mL (which makes sense)If I understood your problem correctly, I hope this makes sense. 0 Likes
