Question

In two moles of acetaldehyde 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:

A- one mole of carbon exactly 12 gram of pure carbon 12 powder is known as 1 mole the number of atom of carbon 12 present in this one mole sample is 6.022 1367*10 power 23 this number is known as avagardros number.

B- moles are the way of counting molecules one mole of a substance equal 6.022*10power23 hydrogen gas being a diaatomic molecules is 2.016g/mol.

C- 1 mole of oxygen =22.4litre

D- I don't know this

I hope this will help you and don't forget to follow me OK thanks

Answer 2

Answer:

molecular mass of C2H4O= 12*2+1*4+16=44g

amount of acetaldehyde= 44*2= 88g

no. of molecules of acetaldehyde= no of moles * avogadro no

=2* 6.022*10^23

=12.044*10^23 molecules

Explanation:

d is the answer
