To calculate molar mass, you use the following formula.Molar Mass = Given mass / number of moles.For example if you are given that there is 85 gram of ammonia and it is 5 moles. Then Molar Mass = 85/5 = 17 g.
You can use an online tool to calculate the molar mass of CoCl3 - convertunits.com/molarmass/CoCl3
29.13 g/mol
The molar mass of potassium sulfide is approximately 110 g/mol.
174.259 g/mol
The molar mass of anhydrous sodium carbonate is 105,9888 g.
The molar mass of lauryl alcohol (C12H26O) is 186,34.
The average atomic mass of an element is the weighted average mass of an atom (including all its isotopes). This is related to the molar mass, because molar mass is the weight of 1 mole of something (atoms, molecules, etc...). 1 mole = 6.022 x10^23 = avogardro's constant.
By taking the wieghted averages of naturally occurring isotopes of that element. :)
You ca calculate the molar mass for an anhydrous compound or for the hydrated forms; it is your choice and depends on the available reagent.
The molar mass is:39,0983 (atomic weight of K) + 54,938044 (idem for Mn) + (15,999 . 4 for O) = 157,432344 g
Molar mass of iron is 56g. Given mass of iron= 112g No. of moles = Given mass/Molar Mass => 112g/56g= 2 moles
