When 3 grams of C is burnt in 8 grams of $O_2$ 11 grams of $CO_2$ is formed what mass of $CO_2$ will be formed when C = 3g and $O_2$ = 5g?​

Answer 1

Answer:

Mass of $CO_2$ formed = 8g

Explanation:

Given that,

When 3 grams of C is burnt in 8 grams of $O_2$ 11 grams of $CO_2$ is formed

Equation:

C + O2 = CO2

here,

we can see that

when 1 mole of carbon and

1 mole of oxygen molecule combines to form 1 mole of carbon dioxide

and

mass of formed CO2 is equal to the total mass of reactants

now we have,

C = 3g and $O_2$ = 5g

so,

mass of $CO_2$ = 3g + 5g

= 8g

so,

Mass of $CO_2$ formed = 8g

Answer 2
