4. how many moles are in 54.0 grams of silver?
54.0 g ag x (108mol ag /1 g ag ) = 5,832 ag moles ag
(use the gray boxes to insert the values for the conversion factors.)
5. what is the mass of 6.3 moles of sulfur?
6.3 mol s x ( / ) = g s
6. how many atoms are in 6.0 moles of argon?
6.0 mol ar x ( / ) = atoms of ar
7. how many moles of kr are in 112 g of krypton?
112 g kr x ( / ) = moles of kr
8. how many moles are in 1.93 x1024 formula units of kf, potassium fluoride?
1.93 x1024 formula units x ( / ) = mol kf
(the next two problems need 2 step conversions - so there are two conversion factors (fractions) for the problem - remember the mole map - covert to moles first, then to the desired unit.)
9. how many atoms are in 86.2 g of si (silicon)?
86.2 g si x ( / ) x ( / ) = atoms of silicon
10. what is the mass in grams of 4.8 x 1024 atoms of magnesium?
4.8 x 1024 atoms of mg x ( / ) x ( / ) = g mg
