How many moles of naci are in 250.0 ml of a 0.35 m nacl solution?

The number of moles of NaCl in the solution are 0.0875 moles.

Explanation:

To calculate the number of moles of NaCl, we use the equation that is used to calculate molarity, which is:

We are given:

Molarity of NaCl solution = 0.35 mol/L

Volume of solution = 250 mL = 0.250 L      (Conversion factor:  1L = 1000 mL)

Putting values in above equation, we get:

Hence, the number of moles of NaCl in the solution are 0.0875 moles.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
