Answer:
Since KOH is a strong base, the solution completely ionizes into K+ and OH- when in water. The reaction KOH --> K+ + OH- takes place. The concentration of [ OH- ] can then be used to calculate the pOH of the solution. pH = 14 - pOH = 14 - 1.48 = 12.52
Explanation:
Answer:
B
Explanation:
Because it is viewed in a different place
1 cm of copper. This is because copper atoms are heavier than aluminum atoms.
Density is the mass divided by the volume of the object

you know denisty and you know mass so you can determine volume if you rearrange the formula

however, when you're doing the division, make sure the units match, since density is given in grams and mass is given in kilograms
once you have volume in cm3, convert that into "dl"
