Question

What mass in grams is represented by :
❤a) 4 mol CO₂
❤b) 0.4 mol NH₃
❤c) 5 mol H₂SO₄

Answer 1

Answer:

0.4 mols of CO2 × 44g/1 mol of CO2

Answer is 17.6 grams

Explanation:

Given data:

No. Of moles= 0.4 mol

Molar mass of co2= 12+16×3= 44 g/mol

Required:

Mass in grams=?

Solution:

As we know,

No.of moles= mass in g/molar mass

So, mass in g= no.of moles × molar mass

Mass in g = 0.4 mol × 44 g/mol

Hence,

Mass in g = 17.6 g
