5.00 ml is withdrawn from a 1.00l solution of nacl and diluted to 100.00 ml. if the concentration of the nacl in the 100.00 ml solution is 0.076, what is the concentration of nacl in the original 1.00 l solution? answers

The concentration of NaCl in 1.00 L of solution is 0.0076 M.

Explanation:

To calculate the molarity of the concentrated solution, we use the equation:

where,

are the molarity and volume of the concentrated solution

are the molarity and volume of diluted solution

We are given:

Conversion factor used: 1L = 1000 mL

Putting values in above equation, we get:

Hence, the concentration of NaCl in 1.00 L of solution is 0.0076 M.

idk what the question is about

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
