Answer:
363.64g of oxygen would be required.
Explanation:
1) Write and balance the combustion equation for propane.
Propane + Oxygen --> carbon dioxide + water
C3H8 + O2 --> CO2 + H2O
Upon balancing, we have;
C3H8 + 5O2 --> 3CO2 + 4H2O
2) How many grams of oxygen are required to burn 200 grams of propane.
From the reaction;
Propane = (3 * 12) + (8 * 1) = 44
Oxygen = (5 * 16) = 80
80 grams of oxygen is required to combust 44g of propane.
80 = 44
x = 200
x = ( 80 * 200 ) / 44
x = 363.64g

Answer:
Here's a quick conversion before I answer your question, use it whenever needed.
1 moles Copper to grams = 63.546 grams. 2 moles Copper to grams = 127.092 grams. 3 moles Copper to grams = 190.638 grams. 4 moles Copper to grams = 254.184 grams. 5 moles Copper to grams = 317.73 grams. 6 moles Copper to grams = 381.276 grams. 7 moles Copper to grams = 444.822 grams.
Ok, now I'll answer your question.
Atomic masses are given in atomic mass units. One atomic mass unit is equal to one gram per mole. When you add these together for a compound, you get the molar mass of that compound. For example, silicon dioxide consists of one silicon atom and two oxygen atoms. The atomic mass of silicon is 28 grams and the atomic mass of oxygen is 16 grams.
(Hope the conversion and the answer helped) Sky
