Answer:
Explanation:
Hey there!
From question;
The molecular mass of NH₄OH is 35.
Avogadro number = 6.023*10²³ molecules.
Then,
From mole concept,
Molecular mass = Avogadro number
So, 35 grams contains 6.023*10²³ molecules.
1 gram contains [tex]\frac{ 6.023*10^{23} }{35}[/tex] molecules.
52.1 grams contains [tex]\frac{6.023*10^{23} }{35} *52.1[/tex] molecules.
Therefore, 52.1 grams contains 8.96*10²³ molecules.
Hope it helps!
