How many moles of NO3 are there in 6.2g?

Sagot :

6.2 divided by the mass number of NO3 is 0.1 moles. Anytime your trying to find the moles of something you divide it by the mass number of your combined elements.

Answer : The number of moles of [tex]NO_3[/tex] is, 0.1 moles

Solution : Given,

Mass of [tex]NO_3[/tex] = 6.2 g

Molar mass of [tex]NO_3[/tex] = 62 g/mole

Now we have to calculate the moles of [tex]NO_3[/tex].

[tex]\text{Moles of }NO_3=\frac{\text{Mass of }NO_3}{\text{Molar mass of }NO_3}=\frac{6.2g}{62g/mole}=0.1moles[/tex]

Therefore, the number of moles of [tex]NO_3[/tex] present in 6.2 g is, 0.1 moles
