Masa= 2,76 V=0,82 T= 300K P=3atm
P.V=R.n.T
3 x 0,82 = 0,082 x n x 300
n = 0,1 n = m/M m= masa / M=masa molecular
0,1 = 2,76 / 10,8x + y
1,08x + 0,y = 2,76 X=2 Y=6 COMPUESTO = C2H6
10.-
V = 500 ml = 1/2L C2H4 T = 300K P = 1248 mmhg
P.V=R.n.T
1248 x 1/2 = 62,4 x n x 300
n = 0,03 n x NA --- 0.03 x (6.02x1023) = 0.1806 -----(0.1806x1023 )x 6 = 1.083x1023
