Question

6. How many molecules are in 2.7 moles of carbon dioxide

Answer 1

A mole is -6.022 • 10 to the 23 power of something.

So, saying you have a mole of iron atoms is like saying you have 6.022 • 10 to the 23 power iron atoms

There for you have 1.63 • 10 to the 24 power

Answer 2

2.7×6.022×10^23

=16.594×10^23 moleclules

Step-by-step explanation:

number of mol= 2.7

1 mol of any element=6.022×10^23

therefote 2.7 mol =2.7×6.022×10^23

=16.594×10^23
