Explain how will you know the mass of the water in your experiment?

Vera_Pavlovna [14]

Very simple, in the lab, you can determine the mass of water by simply weight it in a balance.

You place air in a sealed can at standard temperature and pressure (stp). you heat it to four times its absolute temperature (k)

pochemuha

By Gayle-Lussac's law, the pressure and temperature of a fixed volume and amount of gas is directly proportional.
Thus,

P/T = constant

So if the temperature is increased four times, the pressure is also increased four times.

the mass by mass percentage of a solution is 20%. find the mass of the solute dissolved in 500g of solution

GuDViN [60]

Answer:

$m_{solute}=100g$

Explanation:

Hello,

In this case, by considering the mathematical definition of by mass percentage of a solute as shown below:

$\%m/m=\frac{m_{solute}}{m_{solution}}*100\%$

We are able to compute the mass of the solute in a 20% solution having 500 g of solution as follows:

$m_{solute}=\frac{m_{solution}*\%m/m}{100\%} =\frac{500g*20\%}{100\%}\\ \\m_{solute}=100g$

Best regards.
