Molarity= moles/Volume => 9/15 = 0.6 mol/L
Answer:
Mass of sample is 99.9 g, density of ample is 11.35 
and temperature of sample is 
Explanation:
Mass is an additive property. Therefore mass of combined sample is summation of masses of two pellets.
Mass of combined sample = (37.2+62.7) g = 99.9 g
Density is an intensive property. Therefore density of combined sample of lead will be same as with density of Pb.
Density of combined sample = 11.35
Temperature is an intensive property. Therefore temperature of combined sample of lead will be same as with individual pellets.
temperature of combined sample =
Hey There!
ideal gas law :
PV = nRT
P = nRT/V
P = (1*0.082)(18+273)/(0.5) = 47.724 atm
For VDW :
(P + a(n/V)²)(V - nB) = nRT
P = nRT/(V - nB) - a(n/V)²
P = 1*0.082*(18+273) / (0.5-1*0.03219) - 1.345*( 1/0.5 )² = 45.62
P = 45.62 atm
Pdif = P2-P1 = 47.724 - 45.62 = 2.104 atm
