Answer:

120g

Explanation:

Based on the reaction, when 1 mole of propane and 5 moles of oxygen react, 3 moles of CO2 and 4 moles of H2O are produced. The ratio of production is 3 moles of CO2 per 4 moles of H2O.

Thus, we need to convert mass of water to moles using its molar mass:

Moles H2O (Molar mass: 18g/mol):

63g H2O * (1mol / 18g) = 3.5 moles H2O

Converting to moles of CO2:

3.5 moles H2O * (3 moles CO2 / 4 moles H2O) = 2.625 moles CO2

Mass CO2 (Molar mass: 44g/mol):

2.625 moles CO2 * (44g / mol) = 115.5g of CO2 are released

<h3>120g </h3>

What is the arrangement of the outer planets? What effect does their placement have on the planets?
Ahat [919]
The solar system's outer planets include Jupiter, Saturn, Uranus and Neptune. Their arrangement does not have any effect on the rest of the planets in the solar system, except for the fact that these planets are not in resonance to each other. 

Hope this helps!
