Answer:
The molar mass of the gas
Explanation:
The ideal gas equation of state is:
PV = nRT
If we measure the volume (V), the pressure (P), and the temperature (T), we use the gas constant R (0.082 L.atm/K.mol) to calculate n (moles of gas):
n = PV/RT
Then, we can divide the mass into the number of moles to calculate the molar mass of the gas:
molar mass = mass/n
Answer:
True
Explanation:
Stars are bright and enormous astronomical bodies that are located at a large distance from the earth. They are made up of the lightest gaseous elements namely hydrogen and helium. These hydrogen atoms undergo the reaction of nuclear fusion, which fuels the energy of the star and allows the star to shine, releasing a large amount of energy. They are located about trillions of miles away from the location of the earth, due to which they appear smaller in size.
Thus, the above-given statement is True.
Given the mass (in grams) of a reactant A, first divide this by the molar mass of A to get the number of moles of A. Then balance the chemical reaction, and divide the number of moles of A by the coefficient of A in the balanced reaction. Next, find the coefficient of the product (B) in the reaction, and multiply this by the result from the previous operation. Finally, multiply by the molar mass of B to get the final answer in grams of the product B.
According to the research, fatty acids, which are long molecules in the form of a hydrocarbon chain, are a component of lipids.
<h3>What are lipids?</h3>
They are hydrophobic and water-insoluble molecules that are formed from the esterification of alcohols with fatty acids.
Lipids are a vital part of the diet of living beings since many vitamins are assimilated in the presence of certain lipids and many fatty acids are essential for animal metabolism.
Therefore, we can conclude that according to the research, fatty acids, which are long molecules in the form of a hydrocarbon chain, are a component of lipids.

Answer:
Your answer will be 118 cm^3.
Explanation:
V1/T1 = V2/T2, so V2 = V1T2/T1. 60C = 333K and 120C = 393K.
V2 = (100cm3)(393K)/(333K) = 118 cm3
