V1
of 11.7 molar of
C1
of HCl is diluted to
250cm3
V2
, then the new concentration C_{2} will be __________.

1.936molesdm−3

0.936molesdm−3

0.125molesdm−3

1.125molesdm−3

Answer 1

Answer to Question #51864, Chemistry, Other

the concentration of the pure HCl used in a chemical reaction is

11.2cm³

V1

of 11.7 molar of

C1

of HCl is diluted to

250cm³

V2

, then the new concentration C_ {2} will be ___________.

1.936molesdm⁻³

0.936molesdm⁻³

0.125molesdm⁻³

1.125molesdm⁻³

Solution:

$$c_1 \times V_1 = c_2 \times V_2$$ $$c_2 = \frac{c_1 \times V_1}{V_2}$$ $$c_2 = \frac{11.2 \times 11.7}{250} = 0.52416 \, \text{M}$$

Answer:

0.52416 M
