How many moles are in N2?

In order to have one mole of things, let’s say particles, you need to have 6.022⋅1023 particles → this is known as Avogadro’s constant and acts as the definition of the mole. So, in one mole of nitrogen gas you have 6.022⋅1023 molecules of nitrogen gas, N2 .

How many moles of molecules are there in 56g of nitrogen?

= 12.046 X 1023 molecules of N2.

How many moles are in 14g of N2?

Answer: 14 grams is the molar mass of nitrogen meaning that one mole of nitrogen atoms is 14 grams. One mole of any substance has 6.02*10^23 atoms/molecules of that subtance therefore there are 6.02*10^23 atoms of nitrogen in 14g of nitrogen.

How many molecules of N2 are in 56.00 grams of N2?

= 12.046 X 10²³ molecules of N2.

How many water molecules are there in one drop of water?

The accepted average volume of a drop of water is exactly 0.05 mL (20 drops per milliliter). It turns out there are over 1.5 sextillion molecules in a drop of water and more than 5 sextillion atoms per droplet.
