Question

M. In two moles of acetaldehyde
(CH CHO) calculate the following
a. Number of moles of carbon
b. Number of moles of hydrogen
c. Number of moles of oxygen
d. Number of molecules of acetaldehyde​

Answer 1

Answer:

Given : 2 moles of C2H2O

Now,

a) no. of moles of carbon = 2×2=4

b) no. of moles of hydrogen = 2×2=4

c) no. of moles of oxygen = 2×1=2

d) no. of molecules of C2H2O = 2 × avogadro number = 2× (6.02×10²³)

= 12.04×10²³
