How do you guys calculate these problems? I don't get the answers !
Limit reagents problems
How many moles of UO2(NO3)2 can be produced by reaction of 0.35 moles U3O8, 1.8 moles HNO3, and 0.2 moles O2 according to the following reaction?
2 U3O8 + 12 HNO3 + O2 6 UO2(NO3)2 + 6 H2O
a) 1.40
b) 0.80
c) 1.05
d) 0.90
e) 1.20
and
Mercury and sulfur react to form HgS. A 3.0 g sample of mercury is reacted with 1.0 g of sulfur. What weight of what substance remains unreacted?
(Atomic weights: Hg = 200.59, S = 32.06).
a) 0.48 g S
b) 0.12 g Hg
c) 0.68 g Hg
d) 0.52 g S
e) 0.64 g S
thanks for help
