A student measures the mass of an 8 cm block of brown sugar to be 12.9 g. What is the density of
1 answer:
Answer:
0.0025g/cm³
Explanation:
Given parameters:
Mass of the brown sugar = 12.9g
dimension of the sugar = 8cm
unknown:
density of the sugar = ?
Solution
Density is defined as the mass per unit volume of a substance. The expression is given below:
Density =
We know the mass of the substance but the volume is unknown:
Volume of the brown sugar = l x bx h = 8x8x8 = 512cm³
Density of the brown sugar = = 0.0025g/cm³

Answer: The value of for chloroform is
when 0.793 moles of solute in 0.758 kg changes the boiling point by 3.80 °C.
Explanation:
Given: Moles of solute = 0.793 mol
Mass of solvent = 0.758
As molality is the number of moles of solute present in kg of solvent. Hence, molality of given solution is calculated as follows.
Now, the values of is calculated as follows.
where,
i = Van't Hoff factor = 1 (for chloroform)
m = molality
= molal boiling point elevation constant
Substitute the values into above formula as follows.
Thus, we can conclude that the value of for chloroform is
when 0.793 moles of solute in 0.758 kg changes the boiling point by 3.80 °C.
Answer: Step 1, Isomerase.
Explanation:
Form the version of palmitic acid in the step one by changing the double bond within alpha and beta carbon by Isomerase.
B and C are Isomers, the molecule only differ in configuration.
