The number of molecules that are contained in the given moles of nitrogen trihydride is [tex]6.26 \times 10^{24}[/tex] molecules.
Given the following data:
- Number of moles = 10.4 moles
Scientific data:
- Avogadro's number = [tex]6.02 \times 10^{23}[/tex]
- The molar mass of nitrogen trihydride = 17.0306 g/mol.
The number of moles.
To determine the number of molecules that are contained in the given moles of nitrogen trihydride:
By stoichiometry:
1 mole of nitrogen trihydride = [tex]6.02 \times 10^{23}[/tex] molecules
10.4 moles of nitrogen trihydride = X molecules
Cross-multiplying, we have:
X = [tex]6.02 \times 10^{23} \times 10.4[/tex]
X = [tex]6.26 \times 10^{24}[/tex] molecules.
