If I had 5 moles of C3H8

How many atoms would i have?

How would I solve this?..My attempt is 5X3= 15 C and 5X8= 40 H
Totaling 15+40 = 55 atoms
Is this correct by any chance?

If you have 5 dozens of C₃H₈ - how many atoms would you have?

660?

Correct! Now we just have to tackle your problem

Using the method you used in answering Borek's question, answer your own keeping in mind that a 'mole' is 6.022*10²³ the same way that a dozen is 12.

ok that makes sense....so my answer would be 3.31x10²⁵ atoms total? It sounds weird...

Only compared to your initial answer
