ANSWER ASAP
Suppose that 10.00 HCl of unknown concentration is neutralized by 20.00 mL of a 1.50 M NaOH solution. Determine the concentration of the HCl solution?


a. 0.0750 M HCl

b. 0.150 M HCl

c. 3.00 M HCl

d. 1.50 M HCl

Answer 1

Answer:

c. 3.00 M HCl

Explanation:

From dilution formula

C1V1 = C2V2

C1=?, V1= 10.0ml, C= 1.5, V2= 20.0ml

Substitute and Simplify

C1×10= 1.5×20

C1= 3.00M
