How do you work out the percentage of each element in sodium hydrogen sulfate ?

1 Answer

Answer:

Work out the #M_r# by adding up the #A_r# values as they occur in the formula, then work out the % contribution each element makes.

Explanation:

Work out the #M_r# by adding up the #A_r# values as they occur in the formula.

I'll use approximate values:

#A_rNa=23#

#A_rH=1#

#A_rS=32#

#A_rO=16#

#M_r# of #NaHSO_4#:

#=23+1+32+(4xx16)=120#

Then work out the % contribution each element makes:

%#Na=(23)/(120)xx100=19.16#

%#H=(1)/(120)xx100=0.833#

%#S=(32)/(120)xx100=26.66#

%#O=(64)/(120)xx100=53.33#
