Hello!
In this case, since the mole fraction relates the moles of solute and the moles of solution, and for sucrose it is:
Whereas we need to compute the moles of both sucrose and water based on their molar masses (342.3 and 18.02 respectively) as shown below:
Thus, the mole fraction sucrose turns out:
Best regards!
High because obvs , ph is around the last letter in the alphabet so the ph is going to be high as well , hope this is correct
The mass of the sample reported is 3.5465 g option e is correct.
Mass is the quantitative measure of the physical body.
The mass of the empty sample container is given as 12 g.
The mass of empty as well as sample containers is given as 15.5465 g.
Therefore, the mass of the sample will be given as :
Mass of sample = mass of a sample as well as empty containers - a mass of empty sample container
= 15.5465 - 12
= 3.5465 g
Therefore, the mass of the sample reported is 3.5465 g option e is correct.

Complete question:
Your question is incomplete, but most probably your full question was, A label on an empty sample container reads 12.00 g. you add in a sample of a compound and the mass of the sample container obtaining 15.5465 g. what should the mass of the sample be reported as?
a) 3.546 g
b) 3.54 g
c) 4 g
d) 4.0 g
e) 3.5465 g
Answer:
Dissolving is when the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules. This break up is caused by coming into contact with the solvent. In the case of salt water, the water molecules break off salt molecules from the larger crystal lattice.

Hydrocarbons
