Question

How much oxygen will be added with 12g of carbon to give 44g carbon dioxide assuming complete combustion reaction

Answer 1

32 g

GiVen:-

• Mass of carbon = 12 g
• Mass of carbon dioxide = 44 g

AnSwer:-

Now,

According to law of conservation of mass,

$\sf \: Mass\: of \:carbon + mass\: of\: oxygen = Mass\: of\: carbon\: dioxide \\ \\ \implies \sf \: 12 g+x=44 g \\ \\ \implies \sf \:x = 44 - 12 \\ \\ \implies \sf \: x = 32g\\\\ \sf \therefore \: So \: mass \: of \: oxygen =32 g$
