Answer : The mass of water produced will be 32.78 grams.
Explanation : Given,
Mass of = 21.9 g
Molar mass of = 72.15 g/mole
Molar mass of = 18 g/mole
First we have to calculate the moles of .
Now we have to calculate the moles of .
The balanced chemical reaction will be,
From the balanced reaction we conclude that
As, 1 mole of react to give 6 moles of
So, 0.3035 moles of react to give
moles of
Now we have to calculate the mass of .
Therefore, the mass of water produced will be 32.78 grams.
There are 30 protons and 39 neutrons in the nucleus.
This must me the isotope of an element with an atomic mass close to 69 u.
The only candidates are Zn and Ga.
Zn has a zinc-69 isotope with mass 68.926 u.
Ga has a gallium -69 isotope with mass 68.925 u.
The isotope is probably

Taking into account the reaction stoichiometry and the definition of STP, 5.4 L of carbon dioxide is produced.
<h3>Reaction stoichiometry</h3>In first place, the balanced reaction is:
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
- C₃H₈: 1 mole
- O₂: 5 moles
- CO₂: 3 moles
- H₂O: 4 moles
The following rule of three can be applied: if by reaction stoichiometry 1 mole of C₃H₈ form 3 moles of CO₂, 0.080 moles of C₃H₈ form how many moles of CO₂?
<u><em>amount of moles of CO₂= 0.24 moles</em></u>
<h3>Definition of STP condition</h3>The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.
<h3>Volume of CO₂ produced</h3>You can apply the following rule of three: If by definition of STP 1 mole of CO₂ occupies 22.4 L, 0.24 moles of CO₂ how much volume does it occupy?
<u><em>volume of CO₂= 5.376 L ≅ 5.4 L</em></u>
Finally, 5.4 L of carbon dioxide is produced.
