You have 47.0 mL of a 2.00 M concentrated or "stock" solution that must be diluted to 0.500 M. How much water should you add?
Inessa [10]

The required volume of water to make the dilute solution of 0.5 M is 188 mL.

<h3>How do we calculate the required volume?</h3>

Required volume of water to dilute the stock solution will be calculated by using the below equation as:

M₁V₁ = M₂V₂, where

  • M₁ & V₁ are the molarity and volume of stock solution.
  • M₂ & V₂ are the molarity and volume of dilute solution.

On putting values from the question to the above equation, we get

V₂ = (2)(47) / (0.5) = 188mL

Hence required volume of water is 188 mL.

Predict (to 3 sig figs) the isochoric specific heat of gaseous SF6 (molar mass 146.06 g/mol) at 1200 K, assuming that at this te
bazaltina [42]

Explanation:

As it is known that SF_{6} molecule is a non-linear molecule. Therefore, its isochoric heat capacity will be as follows.

              C_{v} = \frac{3}{2}R + \frac{3}{2}R + (3 \times 7 - 6)R

                         = \frac{3}{2}R + \frac{3}{2}R + 15R

                         = 18 R

Also,    C_{V} = M \times C_{v}

where,     C_{V} = molar heat capacity

                    M = molecular mass

               C_{v} = specific heat

Hence, calculate the value of C_{v} as follows.

                 C_{V} = M \times C_{v}

               8 \times 8.314 \times 10^{7} = 146.06 \times C_{v}

               C_{v} = 10.2 \times 10^{6} erg. K^{-1}. gm^{-1}

This means that value of isochoric specific heat is 10.2 \times 10^{6} erg. K^{-1}. gm^{-1}.

Yes, we have to assume ideal gas behavior because for ideal gas:

                         dU = nC_{v}dT

Whereas for real gases "\frac{an^{2}}{V^{2}}" has to be added here.
