In this question, the sulfur atom has atomic number 16 and atomic mass 33. The Atomic number represents the number of the proton inside the atoms and atomic mass represent the mass of the atoms. Since electron mass to small, the atomic mass can be interpreted as the sum of neutron and proton. Then, the number of the neutron would be:
mass= neutron + proton
33= neutron+16
neutron = 17

Answer:
70 mL
Explanation:
To solve this problem we can use the C₁V₁=C₂V₂ equation, where the subscript 1 refers to the concentrated solution while subscript 2 refers to the diluted one, as follows:
We <u>input the data:</u>
And <u>solve for x</u>:
Thus the answer is 70 mL.
