Question

Calculate the number of molecules of sulphur (s8) present in 16 g of solid sulphur .

Answer 1

Explanation:

There is no a clear cut definition for it. For some, life is all about building a family and leading "life" as it is. ... For a few, life is all about religious practices. For philosopher like Aristotle life is about happiness: "Happiness is the meaning and the purpose of life, the whole aim and end of human existence."

Answer 2

hey dude !!!!

molar mass of S(8) :

$32 \times 8 = 256g$

1 mole is sulphur molecules :

$256g$

16 g of sulphur:-

$\frac{16}{256} = \frac{1}{16} = 0.125$

1 mole of sulphur 8 molecules :-

$6.023 \times {10}^{23} number \: of \: moles$

$\frac{1}{16} moles \: of \: s \: = 6.023 \times {10}^{23} number \: of \: molecules \: \times \: \frac{1}{16}$

hope this helps you
