Calculate the molecular mass of sugar
Answers
Answer:
Wells calculating the molecular weight of sugar is just like calculating molecular mass of anything else.Since you have asked this question ill tell you how how to calculate the molecular mass of any molecule instead .
To find the molecular mass you are first supposed to write down the molecular formula of that molecule or compound .
for example lets take cane sugar ,its molecular formula would be
C12H22O11
now you can know how many atoms of each elements are there in the given compound like in cane sugar there are 12 carbon atoms 22 hydrogen atoms and 11 oxygen atoms.
now you need to know the atomic weight of these elements for this you can consult to the periodic table you have but its really worth it to know atomic weight of first 20 elements in periodic table.
I have a trick for you just memorize the elements in order and the atomic weight turns out to be to times of atomic number for even ones and two times added to one for the odd ones.its just a trick not a rule so its apllicable only for first 20 elements and even there four of them donot follow it.
So now you know the number of atoms and its weight now you have to calculate the total mass of each element present in the atom and sum them up like
in cane sugar
There are 12 carbon atoms each weighing 12 g per mole . That’s total of 12* 12=144 g per mole of cane sugar.
There are 22 hydrogen atom with each weighing 1 g per mole so that’s total of 22*1=22 g per mole of cane sugar.
There are 11 oxygen atoms each weighing 16 g per mole so making a total of 16*11=176 g per mole of cane sugar.
now you know the mass of each atom involved so just add them up to get the total weight as for cane sugar 144+22+176=212 g per mole of cane sugar.
once you get comfortable you can speed up like
C12H22O11
=12*C+22*H+11*O
=12*12+22*1+11*16
=144+22+176
=342
and just write down the units as gram per mole
