Question

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

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...
