Answer:
The volume of calcium hydroxide solution utilized is 0.0235 mL.
Explanation:
Moles of KHP = 
In accordance with the reaction, 2 moles of KHP react with 1 mole of calcium hydroxide, thus 0.0330 moles of KHP will react with;
of calcium hydroxide
The molarity of calcium hydroxide solution = 0.703 M
Volume of calcium hydroxide solution = V
The volume of the calcium hydroxide solution utilized is 0.0235 mL.
Answer:
The specific gravity of the saturated solution is 2
Explanation:
Specific gravity represents the ratio of the density of a solution, in this case, a saturated potassium iodide (KI) solution, to the density of water. Assuming the density of water is 1:
Specific gravity = Density
Density itself is defined as the mass divided by volume.
In 100mL of water, the mass of dissolve-able KI is:
100mL * (1g KI / 0.7mL) = 143g of KI
This indicates that all 100g of KI dissolves (Mass solute)
With 100mL of water corresponding to a mass of 100g (Mass solvent)
The overall mass of the solution computes to 100g + 100g = 200g
In a volume of 100mL, the solution's density is:
200g / 100mL = 2g/mL.
Specific gravity is a dimensionless quantity, thus the specific gravity of the saturated solution is 2
The density is 1.03 g/cm³.
Explanation: The density of a substance is calculated with the formula:
1 kg = 1000 g therefore 2.06 kg = 2060 g.
1 L = 1000 cm³ thus 2 L = 2000 cm³.
We now find:
Mass = 2060 g
Volume = 2000 cm³.
Thus, the final answer of density is:
1.03 g/cm³.
