Question

In two moles of acetaldehyde (CH3 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

Hey Dear,

◆ Answer -

a) 4 mol of carbon

b) 8 mol of hydrogen

c) 2 mol of oxygen

d) 1.2044×10^24 acetaldehyde molecules

● Explaination -

a) 1 molecule of CH3-CHO contains 2 C-atoms. Therefore, 2 mol of CH3-CHO contains 2×2 = 4 moles of Carbon.

b) 1 molecule of CH3-CHO contains 4 H-atoms. Therefore, 2 mol of CH3-CHO contains 2×4 = 8 moles of Hydrogen.

c) 1 molecule of CH3-CHO contains 1 O-atom. Therefore, 2 mol of CH3-CHO contains 2×1 = 2 moles of Carbon.

d) 1 mole of acetaldehyde contains 6.022×10^23 molecules, thus 2 mol will contain 2×6.022×10^23 = 1.2044×10^24 Acetaldehyde molecules.

Thanks dear...
