Question

I want to ask that how many moles are there in 0.35 kg of no2. i need solution to this question.plz.

Answer 1

Answer:

7.6 moles

Explanation:

Given :

• Given mass of the No2 = 0.35 kg = 350 grams

To find :

• Number of moles in the No2 which has a mass of 0.35 kg

So in this question we have to find the number of moles

Number of moles = given mass / molar mass

Molar mass of N = 14

Molar mass of O = 16

Molar mass of NO2 = 14+2×16

Molar mass of NO2 = 14+32

Molar mass of NO2 = 46u

No.of moles = 350/46

No. Of moles = 7.6 moles

The number of moles are 7.6 moles
