Hi!
• For this you want to convert moles to grams
• To do this you would simply multiple your moles times the atomic mass of potassium
3.25 x 39.098= 127.0685
• So your answer for this should be about 127.07 depending on how you need to round!
Answer,googles helps that no chemical will come into contact with your eyes while an apron prevent your clothes being in touch with your clothes
Explanation:
The distance between molecules INCREASES when the substance vaporizes
Explanation:
The distance between the molecules increase due to the fact that as you put more energy into the substance the kinetic energy of the molecules increases. This means they are vibrating more vigorously and the collision between the molecules are becoming more energetic. This means the collisions fling the molecules far away from each other (due to their increased momentum) hence the increased average distance between molecules.

The neutralization reaction is expressed as:
2KOH + H2SO4 = K2SO4 + 2H2O
We are given the volume and the concentration of the KOH that is used in the reaction. We use this and the relations from the reaction to determine the concentration of the acid.
0.150 mol KOH / L ( .025 L ) ( 1 mol H2SO4 / 2 mol KOH ) = 0.00188 mol H2SO4
Concentration of acid = 0.00188 mol / .015 = 0.125 M of sulfuric acid
