What is the specific heat of ethanol if 4650 j are required to raise the temperature of 250.0g of ethanol from 22.0oc to 29.6 de
Alchen [17]

Answer:

C=2.45\frac{J}{g\°C}

Explanation:

Hello there!

In this case, since the thermodynamic definition of heat in terms of mass, specific heat and temperatures is given by:

Q=mC(T_2-T_1)

We are to calculate the specific heat of the ethanol as shown below:

C=\frac{Q}{m(T_2-T_1)}

Thus, by plugging it the given data we can obtain:

C=\frac{4650J}{250.0g(29.6-22.00\°C)} \\\\C=2.45\frac{J}{g\°C}

Regards!

Fynjy0 [20]

The saturation level is only nominally dependent on the temperature of the water. At 20 °C one liter of water can dissolve about 357 grams of salt, a concentration of 26.3% w/w. At boiling (100 °C) the amount that can be dissolved in one liter of water increases to about 391 grams, a concentration of 28.1% w/w.

<h3>How do you calculate the solubility of salt in water?</h3>

Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .

<h3>How do you calculate the concentration of salt in water?</h3>

Salt is the solute (the dissolving substance), and water is the solvent (the substance that dissolves another to create a solution). To make a salt solution by weight percent (w/v), you apply the formula w/v = (mass of solute ÷ volume of solution) × 100.
