Answer:

d=9.5g/L

Explanation:

Hello there!

In this case, according to the given information, it i possible for us to calculate the density of this gas via the ideal gas equation, according to the following setup:

PV=nRT\\\\P=\frac{mRT}{V*MM} \\\\\frac{m}{V}=d=\frac{P*MM}{RT}

Thus, we plug in the variables (pressure in atm and temperature in K) to obtain:

d=\frac{113.6368atm*2.02g/mol}{0.08206\frac{atm*L}{mol*K}*(21+273)K} \\\\d=9.5g/L

Regards!

Nitriles can be converted into carboxylic acids. how would you use ir spectroscopy to monitor the progress of this reaction?
Lady bird [3.3K]

Fats or oils are created when the hydroxide group of glycerol combines in a dehydration synthesis process with the carboxyl group of fatty acids.

<h3>What is dehydration ?</h3>

Your body loses more fluids when you are dehydrated than you are taking in. If unattended to, it could get worse and become a serious problem.

When you don't drink enough water or lose more than you take in, you become dehydrated. Sweat, tears, vomiting, urination, and diarrhea all cause fluid loss. Climate, level of physical activity, food, and other variables can all affect how severe dehydration is.

Dark urine, decreased urination, headaches, weariness, dry skin, decreased skin turgor, and poor focus are all indicators of dehydration.
