Answer 1

d.aer = miu.compus/miu.aer, miu.aer = 28,9 g/mol

=> miu.compus = d.aerxmiu.aer

= 2,56x28,9 = 74 g/mol

avem 4,8 g C + 1g H + 1,6g O = 7,4 g compus

notma compusul CxHyOz

7,4 g comp. ...... 4,8g C ..... 1g H .... 1,6g O

74 g ................... 12x .............. y ........... 16z

12x = 48 => x = 4

y = 10

16z = 16 => z = 1

=> Fm = C4H10O
