Question

How many molecules are in 3.5 moles of ethanol

Answer 1

1 mole of Ethanol molecule contains an Avogadro Number of molecules

1 mole of Ethanol molecule contains 6.02 * 10²³ molecules


3.5 moles of Ethanol will then contain: 3.5 * 6.02 * 10²³

= 2.107 * 10²⁴ molecules.

Answer 2

Answer: There are
`2.1077* 10^(24)` number of molecules in the given moles.

Step-by-step explanation:

We are given:

Number of moles of ethanol = 3.5 moles

According to mole concept:

1 mole of a compound contains
`6.022* 10^(23)` number of molecules.

So, 3.5 moles of ethanol will contain =
`3.5* 6.022* 10^(23)=2.1077* 10^(24)` number of molecules.

Hence, there are
`2.1077* 10^(24)` number of molecules in the given moles.
