Answer:
55.845 u
Explanation:
Fe, iron, has 29 neutrons and a atomic mass of 55.845 u
The balanced reaction is
Na2O + H2O --> 2NaOH
If 2.24 moles of sodium oxide react, that means 4.48 moles of NaOH is formed as it is a 1 to 2 stoichiometric relationship.
Now we multiply by the molar mass to get grams.
4.48 moles NaOH * (39.997 grams/1 mole) = 179.2 grams
Your answer is 179. grams.
2 => 6 meters = 600cm
3 => 70 quarts = 17.5 gallon
50 inches = 1.5 meters
2,000 grains = 4.57 ounces
7 tablespoons = 0.027344 gal
