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

3.18*10^24 molecules

Explanation:

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

=3.18199*10^24 molecules.

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

Hope this helps :)

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
