Question

Convert 26.02 x 1023 molecules of C2H8 to grams. Round your answer to the hundredths place.

Answer 1

Answer:

x= 138.24 g

Explanation:

We use the avogradro's number

6.023 x 10^23 molecules -> 1 mol C2H8

26.02 x 10^23 molecules -> x

x= (26.02 x 10^23 molecules  * 1 mol C2H8 )/6.023 x 10^23 molecules

x= 4.32 mol C2H8

1 mol C2H8     -> 32 g

4.32 mol C2H8 -> x

x= (4.32 mol C2H8 * 32 g)/ 1 mol C2H8

x= 138.24 g

Answer 2

The correct answer is 156.69 * 10^46 grams.

How to convert molecules to grams?

• To convert from molecules to grams,
• it is necessary to first convert the number of molecules of a substance by dividing by Avogadro’s number to find the number of moles, and then multiply the number of moles by the molar mass of this substance.
• Avogadro’s number is given as 6.022 x 10^23
