Since there is no weight, I would assume that this is a 100g of pure compound.
Okay so I would be changing the percentage to gram to solve for the mole.
So
40.0g C (1 mol C/12.01 g C) = 3.33 mol C
6.73g H (1 mol H/1.01 g H ) = 6.66 mol H
53.3g O (1 mol O/16.00 g O) = 3.33 mol O
With that, two of our moles is 3.33, so we consider that are our 1, as it is also the lowest. Therefore the empirical formula is CH2O
I think its

Answer:
60 ml
Explanation:
Now, we know that density = mass/volume
Mass of aluminium = 67.5 g
volume of aluminium =?
density of aluminium = 2.70 g/mL
volume of aluminium = mass/density = 67.5/2.70 = 25 ml
Since volume of water in the cylinder = 35 ml
The water rises to ; 35 ml + 25 ml = 60 ml
Those would be called indicators , simply google them and you should find many. I'll leave some examples "bromophenol blue" "Methyl red" and "phenol red".
