To convert the number of moles of H20 to moles of NH3?
1. H=2(1.008)= 2.01
2. 0=1(16.0) = 16.0
Total = 18.01 =# of moles of H20????
then what do I do
Am I doing it right so far?
thank you!
I don't know what you're trying to do but you don't have enough information for me to help.
1. Write the equation and balance it.
2. Using the coefficients (I'll call them a1 and a2, convert H2O to NH3.
a1*molar mass NH3/a2*molar mass H2O
That will work IF I understand what this is about.
To convert the number of moles of H2O to moles of NH3, you need to use the balanced chemical equation between H2O and NH3. Let's assume the balanced equation is:
2H2 + N2 -> 2NH3
From the equation, you can see that 2 moles of NH3 are produced for every 2 moles of H2. Therefore, the conversion factor is 2 moles of NH3 per 2 moles of H2O.
Now, let's calculate the number of moles of H2O you have:
Molar mass of H2O = 2(1.008 g/mol) + 16.0 g/mol = 18.01 g/mol (as you calculated correctly)
To convert from grams to moles, divide the given mass of H2O by its molar mass:
moles of H2O = mass of H2O / molar mass of H2O
= given mass of H2O / 18.01 g/mol
So, if you have the mass of H2O, you can calculate the number of moles of H2O using the formula above. Once you have the moles of H2O, you can use the conversion factor (2 moles of NH3 per 2 moles of H2O) to convert to moles of NH3.
I hope this helps! Let me know if you have any further questions.
