^I meant molar mass of 4* carbons, because there are actually 4 carbons in Sn(CH3CO2)2 Sorry about that.

^I meant molar mass of 3* carbons, because there are actually 3 carbons in Sn(CH3CO2)2
First, determine how much of the 325g is carbon. 324g [(molar mass of 2 carbon)/(molar mass of Sn(CH3CO2)2)] Then, convert grams of C to mole by dividing by C's molar mass. Finally, convert the mole to atoms. You know for every one mole there is 6.022 × 10^23 atoms.
Standard from should be in this format: Ax +By= C http://www.algebra-class.com/writing-equations-2.html
For the first three, you would have to apply the rational zero theorem ((Broken Link Removed) and then use synthetic division ((Broken Link Removed) to see if the remainder is zero. For the last two, you would group the terms and factor out a common factor method(http://www.ch...
