What is 20% of $16.40? to figure any % of another number write the formula...
20/100 = x/16.40 (where x = 20% of 16.40)
20 x 16.40 = 328 (Cross multiply and then divide by 100)
328/100 = 3.28 (The answer is 3.28 or $3.28
or $3.28
Saying that another way let's say we know we want to take $3.28 from $16.40
What is the percentage?
X/100 = 3.28/16.40 (Now we want to cross multiply the 3.28 x 100 )
3.28 x 100 = 328 (Now we divide 328 by 16.40 )
328 / 16.40 = 20 (So we see X = 20)
20/100= .20 or 20%

Can you determine the molecular formula of a substance from its percent composition?
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
