Question

calculate the number of moles o.4 of co2​

Answer 1

Explanation:

Given data:

number of moles= 0.4 mol

molar mass of co2=12 +16×3=44g/mol

Required:

mass in grams =?

solution:

As we know

No. of moles= mass in g/ molar mass

So mass in gram= no. of moles × molar mass

Mass in gram = 0.4 mol × 44g/ mol

Hence ,

mass in g = 17. 6 g
