Answer:
6.8 moles of NO2=....... g of NO2
= 312.8 g
Explanation:
Molar mass : Mass of substance in grams present in one mole of the molecule.
Molar mass of NO2 :
Mass of N + 2(Mass of O)
= 14 + 2(16)
= 14 + 32
= 46 g
Given :
Moles = 6.8 mole
Molar Mass = 46 g
[tex]moles=\frac{given\ mass}{molar\ mass}[/tex]
This can also be written as:
[tex]given\ mass=moles\times Molar\ mass[/tex]
[tex]given\ mass=6.8\times 46[/tex]
[tex]given\ mass=312.8[/tex]
Mass of NO2 In 6.8 moles = 312.8 grams
