A 200.0 ml quantity of 0.9 M HCl was titrated with an NaOH solution to reach the equivalence point. The goal was to determine the concentration of the NaOH solution. if 23.9 ml if the NaOH solution was required, what was the [NaOH]???

Since the acid and base react in a one to one ratio, you can use the equation M1V1 = M2V2 to solve for M2, or the molarity of NaOH.

M1 = 0.9 M HCl

V1 = 200.0 mL HCl

M2 = ?

V2 = 23.9 mL NaOH

(0.9 M)(200.0 mL) = M2(23.9 mL) —> M2 = 7.53 M NaOH

possibly, yes.

explanation:

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
