Question

How many molecules are present in 5.45 moles of NO? Use the space below to show your work.

Answer 1

3.18*10^24 molecules

Step-by-step explanation:

Since 1 mole of any substance consists of 6.022 × 10²³ molecules, simply do

`(5.45 Moles)/(1)*(6.022*10^23 molecules)/(1 mole)`=3.18199*10^24 molecules.

However, remember to include sig figs (3) and round it to 3.18*10^24 molecules

Hope this helps :)

Answer 2

Explanation below:)

Step-by-step explanation:

5.45 mol NO(6.022*10^23 molecules/mol) = 3.18 *10^24 molecules NO

Good Luck!! :)
