There are 4.5 moles of sodium fluoride in 4.5 moles of sodium fluoride.
Moles = Mass/Molar Mass.Using this equation, we can take 25/(1.0 + 19) and find that it is equal to 1.25 moles.Keep in mind that very few significant figures were used for this example (2), and that if accuracy is to be expected, as many as possible should be used.
Balanced equation. 4Na + O2 -> 2Na2O 10 moles Na (2 moles Na2O/4 moles Na) = 5.0 moles Na2O produced
2KClO3 --> 2KCl + 3O2For every 3 moles of oxygen gas produced, 2 moles of potassium chlorate are used.6 moles O2 * (2 moles KClO3 reacted / 3 moles O2 produced) = 4 moles KClO3
The amount of oxygen in the air is about 0.21 moles per liter.
Of course 6 moles.
16 grams of oxygen how many moles is 0,5 moles.
moles of what?
55.8 moles
2 moles of Ca and 4 moles of OH
There are 4.5 moles of sodium fluoride in 4.5 moles of sodium fluoride.
this is a easy one. There are only 0.04166 moles.
The answer is 7,73 moles.
20 moles
The answer is 10 moles.
55.8 moles
