Question

calculate the amount of carbondioxide released when 36gm of carbon reacts with oxygen​

Answer 1

$\huge{\pink{\underline{\underline{Answer:-}}}}$

Given:

36 g of carbon reacts with oxygen to form carbon dioxide

To find:

Amount of carbon dioxide released

Solution:

C + O2 ----> CO2

$\\ \\ mole \: of \: carbon \: formed \: \\ = \dfrac{mass}{molar \: mass\: }$

$\: \\ mole \: of \: carbon \: = \dfrac{36}{12} \\ \\ molar \: mass \: of \: carbon \: is \: 12g \\ \\ mole \: of \: carbon \: formed \: is \: 3 \: mol$

Here,

In C+ O2 ---> CO2

1 mole C gives 1 mole carbon dioxide

3 mole C gives 3 × 1/1 = 3 mole carbon dioxide

Required answer:

Therefore, amount of carbon dioxide released is 3 mole
