grams + moles + rep. particles
Ex 1) Convert 50.0 g of Mg to atoms:
Ex 2) Convert 7.200 x 1024 atoms of He to grams:

Transcribed Image Text:Calculating Molar Masses of Compounds
Just add together the molar masses of all the elements in the
compound (by Conservation of Mass), Distribute through the
parentheses when necessary.
Ex 1) CCI,F,
Ex 2) M9CO, ..
Ex 3) (NH,);PO,
Ex 4) Sn;(PO,),
Molar mass 3 atoms Sn ( 118.7) + 1(4) (31) + 4(4) (16)
= 736.1 g/ mole
