Question

total number of H2 molecules that can be obtained from all hydrogen atoms of 10 formula units of CH3COONH4?​

Answer 1

35

as you need H2 molecules

or 70 if you need Help molecules

hope this helps

Answer 2

Hey Dear,

◆ Answer -

N = 35NA = 2.107×10^25

◆ Explanation -

10 Formula units means 10 moles of CH3COONH4.

From 1 CH3COONH4 molecule, we get 7 H-atoms. Therefore, we'll get 70 mol H-atoms from CH3COONH4.

Each H2 molecule is made of two H-atoms thus 70/2 = 35 mole H2 is formed.

Calculating the number of molecules -

N = n × NA

N = 35 × 6.022×10^23

N = 2.107×10^25 molecules

Therefore, 2.107×10^25 H2-molecules are formed from 10 formula units of CH3COONH4.
