Answer;
= 1.615 moles
Explanation;
The molar mass of NO2
= 46.01 g/mol
The mass of NO2 given is 74.3 g
Number moles = mass/ molar mass
= 74.3 g/ 46.01 g/mol
= 1.615 moles
Answer: The number of moles of [tex]NO_2[/tex] in 74.3 g of [tex]NO_2[/tex] is 1.62 moles.
Explanation:
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
Given :
Mass of [tex]NO_2[/tex]= 74.3 g
Molar mass of [tex]NO_2[/tex] = 46 g/mol
Putting in the values, we get:
[tex]\text{Number of moles of}NO_2=\frac{74.3g}{46g/mol}=1.62moles[/tex]
Thus the number of moles of [tex]NO_2[/tex] in 74.3 g of [tex]NO_2[/tex] is 1.62 moles.
