how to find mass percentage

to find the mass percentage of one component, you divide the its mass to the total mass * 100

for example, if you have initially 20 grams of Na and 30 grams of Fe,

total mass = 20 + 30 = 50

if we want to find mass percentage of Na:

(20/50) * 100 = 40%

for mass percent of Fe:

(30/50) * 100 = 60%

hope this helps~ :)
