Question

What is the mass in grams of 2.0 moles of NO2

Answer 1

Molar mass NO₂ = 46.0 g/mol

1 mole -------- 46.0 g
2.0 moles ----- ?

Mass (NO₂) = 2.0 x 46.0 / 1

=> 92.0 g

hope this helps!

Answer 2

The mass of 2 moles of NO₂ is 92 grams.

Step-by-step explanation:

Given that,

Number of moles, n = 2 moles

We need to find the mass of 2 moles of NO₂. We know that the number of moles is given by the formula as :

`n=(m)/(M)`

m is the given mass

M is the molar mass of NO₂,
`M=14+16* 2=46\ g`

`m=n* M\\\\m=2* 46\\\\m=92\ g`

So, the mass of 2 moles of NO₂ is 92 grams. Hence, this is the required solution.
