Answer:
C20 H14 O2
Explanation:
Remark
This is a sample, which the question does not say and should. It is a fraction of 1 mole. So what you have to do is multiply the numbers given by x and equate it to 286.28
Equation
150,86* x + 8.86*x + 20.1*x = 286.28
179.8x = 286.28
x = 286.26/179.8
x = 1.592
Now multiply the given numbers by 1.592
150.86 * 1.592 = 240.58
8.85 * 1.592 = 14.1
20.1 * 1.592 = 32
Rounding you get
240/12 = 20
14.1/1 = 14
32/16 = 2
C20 H14 O2
Hey there!:
The fractional saturation y is defined as :
y = [ L ] / Kd + [ L ]
where :
[ L ] = concentration of binding ligand
Kd = 400 nm
The base gram of the compound is 16.042
To find the new amount of grams, you need to multiply the amount of moles by the the base grams
16.042*.25=4.01
So one fourth of the compound is 4.01 grams of Carbon tetrahydride.
Here we go ~
Energy difference btween the two electronic states can be expressed as :
[ h = planks constant,
= frequency ]
