Question

How many moles of butane do we have if we have 5.50 x 10^24 molecules of butane (C4H10)?

Answer 1

9.14moles

Explanations:

According to the Avogadro's constant,

`1mole\text{ of }C_4H_(10)=6.02*10^(23)molecules`

We are to determine the moles of 5.50 x 10^24 molecules of butane. This is expressed as:

`\begin{gathered} mole\text{ of }C_4H_(10)=(5.50*10^(24))/(6.02*10^(23)) \\ mole\text{ of C}_4H_(10)=0.914*10^(24-23) \\ mole\text{ of C}_4H_(10)=0.914*10 \\ mole\text{ of C}_4H_(10)=9.14moles \end{gathered}`

Therefore the required mole of butane is 9.14moles
