A chemist wants to make 2.7L of a 0.106M KCl solution.How much KCl in grams should the chemist use?

Determine the volume of 0.170M NaOH solution required to neutralize each of the following samples of hydrochloric acid. The neutralization reaction is:
NaOH(aq)+HCl(aq)→H2O(l)+NaCl(aq)

A)35mL of a 0.170M HCl solution
B)65mL of a 0.055M HCl solution
c)160mL of a 0.835M HCl solution

Here's a similar question that might help:

Sample Question
Determine the volume of 0.135 M NaOH solution required to neutralize each of the following samples of hydrochloric acid. The neutralization reaction is:

NaOH(aq) + HCl(aq) =H2O(l) + NaCl(aq)

-50 mL of a 0.065 M HCl solution : Two sig figs


-160 mL of a 0.905 M HCl solution :three sig figs

Answer
Both of these depend on the equation:
V2 = V1 x M1 / M2

(50 mL) x (0.065 M) / (0.135 M) = 24 mL

(160 mL) x (0.905 M) / (0.135 M) = 1.07 x 10^3 mL

Hope that helped.

Determine the volume of 0.160M NaOH solution required to neutralize each of the following samples of hydrochloric acid. The neutralization reaction is
NaOH (aq) + HCl (aq) Rightwards Arrow H2O (l) + NaCl (aq)

20mL of a 0.160M HCl solution
65mL of a 0.045M HCl solution
160mL of a 0.855M HCl solution
