Answer to Question #350013 in General Chemistry for Toney

Question

When 0.344 mol of HCl is combined with enough water to make a 450.0 mL solution, the concentration of HCl is ________ M.

Question 8 options:

1) 

7.64 × 10^-4

2) 

0.155

3) 

1.31

4) 

0.764

5) 

0.344

Answer 1

C_M — concentration of molarity = ?

n — amount of HCl = 0,344 mol

V — volume of solution = 450 ml = 0,45 l

C_M = n / V = 0,344 / 0,45 = 0,764 mol/l

Answer:

4) 0,764
