Question

multiple Promotion
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
(Ans.: A. 4 mol, B. 8 mol, C. 2 mol,
D. 12.044 x 1023 molecules ).​

Answer 1

Answer:

The formula for acetaldehyde is CH3CHO

In this one mole of acetaldehyde there is 2  moles of carbon, 4 moles of hydrogen and 1 mole of oxygen are present.

For two moles of acetaldehyde all the components will be double.

So that,Number of moles of carbon = 4 mole

Number of moles of hydrogen = 8 mole

Number of moles of oxygen= 2 mole

Number of molecules of acetaldehyde=  12.044 x 10^23 molecules

To calculate the number of molecules,

first take the atomic weight of all the components,

multiply with their moles and them add them together.

divide the mass with a particular mass

then multiply it with the avogadro constant .
