Answer:
Answer is 2.2gram mass of CO2
Explanation:
Mass NO = 3g
Molecular Mass= 14+16=30
ma/mol.mass= moles no.
3/30= 0.1 moles
no of oxygen atoms in NO =0.1 × 6.02 ×10²³atoms =6
6.02×10²²atoms
number of oxygen atoms in NO = Number of oxygen atoms in CO2
moles of CO2 = atoms ofO2 in CO2/ NA
= 6.02 × 10²² / 6.02 × 10²³× 2
= 0.05 moles of CO2
moles × mol mass =mass of compound
0.05× 44 = 2.20 grams
Hope this helps you..
