Question

what volune of 2.00 M HCI will neutralize 100.0 mL of 1.00 M C(OH)2?
a. 400. mL
b. 200. mL
c. 100. mL
d. 50.0 mL
​

Answer 1

200ml

Explanation:

The moles ratio of reacting HCl to C(OH)2 is 2:1. Thus calculate the number of moles of C(OH)2 then multiply it by two. After that, divide the moles of HCl by the molarity of HCl then you'll get the volume of HCl in litres. in order to get the volume in ml multiply the answer by 1000
