Question

SOMEONE HELP ME

Answer 1

Answer:

1. 1.33 gram of carbon

2. 2.38g of carbon dioxide

Explanation:

From the given information:

Total amount of CO₂ = 4.86 grams

Atomic mass of C = 12 g/mole

molar mass of CO₂ = 44 g/mole

∴

The mass of the Carbon (C) in grams is:

$= Total\ amount \ of \ CO_2 \times \dfrac{12 \ g/mol}{44 \ g/mol}$

$= 4.86 \ g \times \dfrac{12 \ g/mol}{44 \ g/mol}$

= 1.33 gram of carbon

2.

Here, the total amount of CO₂ = unknown

Atomic mass of O₂ = 32 g/mole

molar mass of CO₂ = 44 g/mole

amount of oxygen = 1.73 g

∴

The mass of CO₂ = $Total \ amount \ of \ O_2 \times \dfrac{44 \ g/mol}{32\ g/mol}$

$=1.73 \times \dfrac{44 \ g/mol}{32\ g/mol}$

= 2.38 g of carbon dioxide
