Question

Determine the number of molecules present in 4.56 mol of nitrogen (n2).

Answer 1

we can calculate this by using Avogadro's number which is 6.022 x 10²³.
1 mole of nitrogen contains = 6.022 x 10²³ molecules
4.56 moles of nitrogen contains = 4.56 x 6.022 x 10²³
2.75 x 10²⁴ molecules are present in 4.56 moles of nitrogen.
