Answer:

m_{solute}=0.85g

Explanation:

Hello there!

In this case, according to the given information for the parts per million of methane in this solution, it is possible for us to first write the equation for this unit of concentration as shown below:

ppm=\frac{m_{solute}}{m_{solvent}} *1x10^6

In such a way, since the septic tank has a mass of 50,000 g, the mass of methane into it is calculated as shown below:

m_{solute}=\frac{ppm*m_{solvent}}{1x10^6}

Now, we plug in the numbers to obtain:

m_{solute}=\frac{17*50000g}{1x10^6}\\\\m_{solute}=0.85g

Regards!

Write the information obtained from solubility curves.​
salantis [7]

Explanation:

The solubility curve helps us to compare the solubility of difference substances at same temperature. It gives the idea that solubility changes with the temperature. The solubility curve helps us to predict which substance will crystalize out first from hot solution containing two or more solutes.
