# Mass of “orange” in 25% orange juice [closed]

Hypothetical question:
Knowing that orange juice has 25% concentration of orange. And knowing mass of juice which is 200g. What is mass of oranges included in juice?

Assuming that orange is a molecule, am I right that mass in 25% juice would be 25% x 200g = 50gram?

I am thinking about simple formulas, without mols on basic level.
If I know mass of entire liquid and know that 25% of acid is a concentration, so do I have to simply computer percentage, or rather computing for acid and rest differently?

• No. Molecular mass doesn't change with concentration alteration. (Your question is sounding a little bit wierd to me) – M.A.R. ಠ_ಠ Feb 5 '15 at 20:25
• Are you asking how many grams of a molecule in orange juice would be expected from 25% juice? Perhaps with the assumption that the juice is made up of the same compound? – Melanie Shebel Feb 6 '15 at 2:15
• @Melanie Shebel, it sounded like that was what was being asked at first. That's not what's being asked now. – Fred Senese Feb 6 '15 at 17:16
