To find this answer you take the mass of the carbon in the compound and divide it by the mass of the entire compound, the one closest to 40% is the correct answer.
I will do hexose for you and you can do the rest of them
mass hexose = 6*12 + 12*1 + 6*16 = 72 + 12 + 96 = 180
mass C in hexose = 6 * 12 = 72
% C in hexose = 72/180 * 100% = 40% (This may be your answer unless you have multiple answers for this one)
Answer:
<h3> 5.87/26.86=77.31/...</h3>
Explanation:
after solving this u can find the answer in easy way
According to Raoult's law, Vapor pressure is directly proportional to the mole fraction of the solution. As 1.0 M CaF2 has least moles here, it has lowest vapor pressure.
In short, Your Answer would be Option D
