8 0

Answer:

2.13g

Explanation:

Atomic mass of CO2 =  12 + 32 = 44g/Mol

Atomic mass of C3H8 = 36 + 8 = 44g/Mol

Reaction

C3H8 + 5O2 --> 3CO2 + 4H2O

3CO2 = 6.39g

Required C3H8 = (6.39/(44 x 3)) x 44 = 2.13g

What is the mass of carbon dioxide formed when 36g of carbon is burnt?<br> C+O2 -------&gt;C02
Anestetic [448]

Answer:

Mass = 132 g

Explanation:

Given data:

Mass of CO₂ formed = ?

Mass of C burnt = 36 g

Solution:

Chemical equation:

C + O₂    →    CO₂

Number of moles of carbon:

Number of moles = mass/molar mass

Number of moles = 36 g/ 12 g/mol

Number of moles = 3 mol

now we will compare the moles of carbon and carbon dioxide.

                C           :        CO₂

                 1           :         1

                3           :         3

Mass of CO₂:

Mass = number of moles × molar mass

Mass = 3 mol × 44 g/mol

Mass = 132 g
