The compound that has the highest molecular weight based on the chromatogram is the compound with Rf 0.25.

A chromatogram is an output that shows the extent of separation of the components of a mixture. If the Rf is high, then it means that the substance traveled a large distance through the plate and vice versa.

Similarly, the molecular mass of the substances correlate with the Rf value observed for each component. The components with high molecular mass always show a low Rf value.

This implies that the lowest Rf value corresponds to the largest relative molecular mass. Thus, the compound that has the highest molecular weight based on the chromatogram is the compound with Rf 0.25.

34. 3.15 mol of an unknown solid is placed into enough water to make 150.0 mL of solution. The solution's temperature increases
Digiron [165]

Answer:

ΔH = 2.68kJ/mol

Explanation:

The ΔH of dissolution of a reaction is defined as the heat produced per mole of reaction. We have 3.15 moles of the solid, to find the heat produced we need to use the equation:

q = m*S*ΔT

<em>Where q is heat of reaction in J,</em>

<em>m is the mass of the solution in g,</em>

<em>S is specific heat of the solution = 4.184J/g°C</em>

<em>ΔT is change in temperature = 11.21°C</em>

The mass of the solution is obtained from the volume and the density as follows:

150.0mL * (1.20g/mL) = 180.0g

Replacing:

q = 180.0g*4.184J/g°C*11.21°C

q = 8442J

q = 8.44kJ when 3.15 moles of the solid react.

The ΔH of the reaction is:

8.44kJ/3.15 mol

= 2.68kJ/mol
