Answer:

Explanation:   There can be may ways to separate a mixture of sulfur, gold and ethanol nut one of the simplest ways are written below-

As we know that the sulfur as well gold both are soluble in ethanol but the solubility of gold in ethanol is more than that of solubility of sulfur.

Gold dissolved in ethanol can be easily collected by the means of steam condensation. and in this way sulfur can be separated.

Now the steams can be condensed off in order to get the gold so that the two of them could get separated.

likoan [24]
We know that molarity = mol/L, so:

1.5 M = x mol/0.345 L

1.5 M * 0.345 L = x mol => 0.5175 mol

0.5175 mol/0.250 L = 2.07 M

Your new molarity of the solution will be 2.07 M.

Rainbow [258]
Hello!

The pressure of the gas when it's temperature reaches 928 °C is 3823,36 kPa

To solve that we need to apply Gay-Lussac's Law. It states that the pressure of a gas when the volume is left constant (like in the case of a sealed container like an aerosol can) is proportional to temperature. This is the relationship derived from this law that we use to solve this problem:

P2= \frac{P1}{T1}*T2= \frac{103 kPa}{25}*928=3823,36 kPa

Have a nice day!
