a) q = M/Vm M = qVm = 0,8928·22,4 = 20g/mol gazul = neon
b) T = 340K P = 17atm q = 39,0243g/l
PV = nRT = m/M ·RT PM = m/V ·RT PM = qRT M = 39,0243·0,082·340/17
M = 64g/mol A (X )+ 32 = 64 A (X) = 32 A = sulf
c) M = 2,21845·32 = 71g/mol A = 35,5g/mol A = clor
d) M = 1,4532·28,9 = 42g/mol 14n = 42 n = 3 D = C3H6
e) m = 10,95g V = 6,72 l m/M = V/Vm M = m·Vm / V = 10,95·22,4/6,72
M = 36,5 E = HCl
