Answer:

1.25 mol LiF

Explanation:

5.00 M solution means

5.00 mol LiF in 1 L solution=1000mL

x mol LiF        in                        250 mL

x = 5.00*250/1000 = 1.25 mol LiF

A mixture of 0.220 moles CO, 0.350 moles H2 and 0.640 moles He has a total
emmasim [6.3K]

Answer:

P(H₂) = 0.8533 atm

Explanation:

n(CO) = 0.220 mole

n(H₂)  = 0.350 mole

n(He) = 0.640 mole

_______________

∑ n  =  1.210 moles

mole fraction => X(H₂) = 0.350/1.210 = 0.2892

Dalton's Law of Partial Pressures => P(H₂) = X(H₂)·P(ttl) = 0.2892(2.95 atm) = 0.8533 atm
