Question

6.8 miles of NO2= g of NO2

Answer 1

6.8 moles of NO2=....... g of NO2

= 312.8 g

Step-by-step 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

`moles=(given\ mass)/(molar\ mass)`

This can also be written as:

`given\ mass=moles* Molar\ mass`

`given\ mass=6.8* 46`

`given\ mass=312.8`

Mass of NO2 In 6.8 moles = 312.8 grams
