Calculate the vapor pressure at 25 ?c of hexane above the solution. the vapor pressure of pure hexane at 25 ?c is 151 torr.
Studentka2010 [4]
One of the many ways in order to solve for the vapor pressure of pure components at a given temperature is through the Antoine's equation which is written below,
                                    P = 10^(A - B/C+T)
where A, B, and C are constants and T is the temperature in °C and P is the vapor pressure in mm Hg. 
For hexane,
                             A = 7.01
                             B = 1246.33
                             C = 232.988

Substituting the known values,
                            P = 10^(7.01 - 1246.33/232.988+25)
                             <em> P = 151.199 mm Hg</em>

A patients blood is tested for growth hormone which has a molecular mass of 848.952g/mol. The test results show a normal concent
rusak2 [61]

Answer:

\boxed{4.7\times 10^{-9}}

Explanation:

Data:

MM = 848.952 g/mol  

   c = 4.0 x 10⁻⁶ g/L

  V = 1 L

Calculations:

(a) Mass of growth hormone

\text{Mass} = \text{1 L} \times \dfrac{4.0 \times 10^{-6} \text{ g}}{\text{1 L}} = 4.0 \times 10^{-6} \text{ g}

(b) Moles of growth hormone

\text{Moles} = 4.0 \times 10^{-6} \text{ g} \times \dfrac{\text{1 mol}}{\text{848.952 g}} = 4.7\times 10^{-9}\text{ mol}\\\\\text{There are $\boxed{\mathbf{4.7\times 10^{-9}}\textbf{ mol}}$ of growth hormone in 1 L of blood.}

The diameter of a chlorine atom is 200. pm. How many chlorine atoms are required to line up end to end to stretch a distance of
BartSMP [9]

The number of chlorine atoms needed would simply be the ratio of distance and diameter. But first convert 200 pm to mm:

<span>200 pm = 2 E-7 mm              </span>

So the number of chlorine atoms needed is:

<span>1.0 mm / (2 E-7 mm) = 5,000,000 Chlorine atoms = 5 E6 atoms</span>
