Answer:
About 0.1738 liters
Explanation:
Using the formula PV=nRT, where p represents pressure in atmospheres, v represents volume in liters, n represents the number of moles of ideal gas, R represents the ideal gas constant, and T represents the temperature in kelvin, you can solve this problem. But first, you need to convert to the proper units. 215ml=0.215L, 86.4kPa is about 0.8527 atmospheres, and 15C is 288K. Plugging this into the equation, you get:
![0.8527\cdot 0.215=n \cdot 0.0821 \cdot 288\\n\approx 7.754 \cdot 10^{-3}](https://tex.z-dn.net/?f=0.8527%5Ccdot%200.215%3Dn%20%5Ccdot%200.0821%20%5Ccdot%20288%5C%5Cn%5Capprox%207.754%20%5Ccdot%2010%5E%7B-3%7D)
Now that you know the number of moles of gas, you can plug back into the equation with STP conditions:
![1V=7.754 \cdot 10^{-3} \cdot 0.0821 \cdot 273\\V\approx 0.1738L](https://tex.z-dn.net/?f=1V%3D7.754%20%5Ccdot%2010%5E%7B-3%7D%20%5Ccdot%200.0821%20%5Ccdot%20273%5C%5CV%5Capprox%200.1738L)
Hope this helps!

Bread dough rises due to the formation of gas.
<u>Explanation:</u>
- If we observe the outer part of the bread, which contains tiny hole like structure, due to the gas formation inside the bread dough.
- In the bread dough rising process, the industries are using the yeast, which makes the gas that separates the protein particles in the bread move apart and makes the dough of the bread rise.
- In this reaction, the yeast utilizing the carbohydrate to make a gas namely carbon-di-oxide gas which makes the dough to rise
Answer:
The density is 1,35 g/cm3
Explanation:
We use the formula for calculate the density
δ =m/V =12,2g / 9,0 cm3= 1,35 g/cm3
