Answer:
Empirical formula is C₃H₄O
Explanation:
Empirical formula:
It is the simplest formula gives the ratio of atoms of different elements in small whole number
.
Given data:
Percentage of hydrogen = 7.14%
Percentage of carbon = 64.3%
Percentage of oxygen = 28.6%
Empirical formula = ?
Solution:
Number of gram atoms of H = 7.14 / 1.01 = 7.1
Number of gram atoms of O = 28.6 / 16 = 1.8
Number of gram atoms of C = 64.3 / 12 = 5.4
Atomic ratio:
C : H : O
5.4/1.8 : 7.1/1.8 : 1.8/1.8
3 : 4 : 1
C : H : O = 3 : 4 : 1
Empirical formula is C₃H₄O.
C10H8N2O2S2
C=12,H=1,N=14,O=16,S=32
R. F. M (Relative Formula Mass)=(12*10)+8+(2*14)+(2*16)+(2*32)
Number of moles =given mass/formula mass
=29/252
=0.1151 moles
