The equation to find the percentage by mass of a solution is:

(Mass of solute/mass of solution) x 100 = percentage by mass

So, let's identify the variables.

Mass of solute: 22g

Mass of solution: 112g

The reason that the solution is 112g and not 90g is because the solution needs to include the mass of the solute and solvent, meaning 90 + 22 is the mass of the solution.

(22/112) x 100 = 19.6%

SVETLANKA909090 [29]

Answer:

The temperature in degress Celsius is 52.25°C

Explanation:

According the equation:

$V(\rho _{a} -\rho _{t})g=mg\\\rho _{a} -\rho _{t}=\frac{n}{V} =\frac{340}{2950} =0.115kg/m^{3}$

$\rho _{t}=\rho _{a} -0.115=1.2-0.115=1.085kg/m^{3}$

The temperature is:

$T=\frac{P}{\rho _{t} R} =\frac{1.013x10^{5} }{1.085*287.05} =325.25K=52.25$ °C

I think it’s microbiology, since it would help the student understand the process of composting the best. Botany is plants- not for composting. Geophysics- he’s not researching tectonic plates. Oceanography- he isn’t interested in the marina trench
