If ammonia (NH3) has a molar weight of 17 grams per mole, then 10 moles means 17x10=170 grams.
moles = weight (in g) / molecular weight = 5 / 90 = 0.056 moles
moles = weight in grams / molecular weight = 59.1 / 119.38 = 0.5 moles
So here, you have to divide by the molecular weight. The molecular weight is 146g/mol. 16.3/146 is 0.11164 moles
Number of moles = weight (in g) / molecular weight = 6.80 / 101.961 = 0.0667 moles or 66.7 milli moles.
1.5444 moles (divide by molecular weight)
molecular weight
Ammonia = NH3Molecular mass = 16.0Formula of grams to moles: grams / molecular mass = moles170,000 g / (16.0) = 10,600 moles NH3Note that the answer is with three significant digits
HClO3 molecular weight is 84.46g/mol. moles is mass/molecular weight. 1.25/84.46 is 0.0179999 moles
moles = weight (in g) / molecular weight = 5 / 90 = 0.056 moles
moles = weight in grams / molecular weight = 59.1 / 119.38 = 0.5 moles
So here, you have to divide by the molecular weight. The molecular weight is 146g/mol. 16.3/146 is 0.11164 moles
no. moles = mass / molecular weight molecular weight = 64.06 mass = 28.4 28.4 / 64.06 = .4433moles sulphur
moles = weight in grams / molecular weight = 56 / 28 = 2 moles
Number of moles = weight (in g) / molecular weight = 6.80 / 101.961 = 0.0667 moles or 66.7 milli moles.
1.5444 moles (divide by molecular weight)
moles = weight (in g) / molecular weight (in g/mol) = 74.3 / 161.97 = 0.46 moles
moles can be used to calculate gmv(gram molecular weight)
