Answer:
1.19mole
Explanation:
Given parameters:
Mass of potassium hydroxide , KOH = 66.48g
Unknown:
Number of moles of KOH = ?
Solution:
To solve this problem, we need to use the expression below;
Number of moles =
Molar mass of KOH = 39 + 16 + 1 = 56g/mol
Number of moles = = 1.19mole
Answer:
same density
Explanation:
The amount of methanol is a quantitative characteristic, and by the other side the density of methanol is a qualitative characteristic. What I mean is that the amount of methanol is not related to the density; it would be the same density no matter how much methanol you have.
