Answer:
Ok so I dont have a paper on me, but to solve this, first you need to know, 1 ml is 1 cubic centimeter, okay so we need to find the volume, which is 4/3 times pie times r cubed, the answer to this equation will then bet 51 cubic centimeters which directly translate to 51 ml pushed out of the full cup
So,
To find the number of moles in 90g of NaOH, what we do is to divide the given amount by the molar mass of NaOH.
The molar mass of NaOH is 40g/mol.
So,
Therefore, the correct answer is A. 2.25moles
