<span>How many electrons would it take to equal the mass of a proton:
Here's one way of finding the value of it:
=> number of electrons is equivalent to 1 proton.
Let's have an example.
1.6726*10 -24g
_______________
1 proton
______________
9.109*10- ^28g
_______________
1 electron
Based on the given example above, the electrons is 1 839 per 1 proton.
It's about 1800 electrons/proton.</span>

Options are;
A: measuring cylinder, metre rule
B: measuring cylinder, stopwatch
C: metre rule, balance
D: metre rule, stopwatch
Answer:
A: measuring cylinder, metre rule
Explanation:
Usually, when measuring volume of a small material, we make use of a piece of laboratory apparatus known as measuring cylinder which is also known as graduated cylinder.
Since it is a graduated cylinder, it means we will make use of metre rule.
Thus, the correct option is option A.
