Answer:
a. 6.57 cm
b. 8.17 cm
c. 0.80
Explanation:
a. The compound moved from where it was first placed, to a spot 7.57 cm from the bottom of the paper, in other words:
- 7.57 cm - 1.00 cm = 6.57 cm
b. A similar method is made for the solvent:
- 9.17 cm - 1.00 cm = 8.17 cm
c. The Rf of the factor is equal to the <u>distance that the compound moved divided by the distance the solvent moved</u>:

Options for given question are as follow,
<span>It has the largest volume.
It has the most solute for a given volume.
It has the greatest amount of solute.
It has the most volume for a given amount of solute.
Answer:
Option B (</span>It has the most solute for a given volume) is the correct answer.
Explanation:
Concentration of solution is the amount of solute dissolved per volume. Amount of solute and concentration are directly related when volume is kept constant while, volume and concentration are inversely related when amount of solute is kept constant.
In option-B it is clearly given that the volume is kept constant and the amount of solute is being increased. Hence, it is the best choice.
Answer:
Empirical formula is C₃H₃O
Explanation:
Given data:
Mass of ethyl butyrate = 1.95 mg
Mass of CO₂ = 4.42 mg
Mass of water = 1.81 mg
Empirical formula = ?
Solution:
Percentage of C = 4.42/1.95 × 12/44×100
= 2.27× 0.273 ×100
= 62
percentage of H = 1.81/1.95 × 2/18 × 100
= 0.93 × 0.11 ×100
= 10.23
percentage of oxygen = 100 - (72.23)
= 27.77
number of gram atoms of C = 62/12 =5.17
number of gram atoms of H = 10.23 / 2 =5.115
number of gram atoms of O = 27.77 / 16 =1.74
Atomic ratio:
C : H : O
5.17/1.74 : 5.115/1.74 : 1.74/1.74
3 : 3 : 1
Empirical formula is C₃H₃O
