The concept of an ideal gas is chiefly used to explain the behavior of a gas sample according to the ideal gas law. It's not primarily used to determine the mass of a gas sample, or whether a gas is monatomic or diatomic.
The concept of an ideal gas is primarily used to explain the behavior of a gas sample. An ideal gas is a theoretical gas composed of randomly moving, non-interacting point particles. It follows the ideal gas law which is PV=nRT, where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T is the absolute temperature. The ideal gas law allows us to predict how a gas will behave under different conditions of pressure, volume, and temperature.
The mass of a gas sample is inherently tied to the moles of gas, per the molar mass concept in the ideal gas law. As for whether a gas is monatomic or diatomic, this depends on the atomic structure and bonding of the specific gas species, and not the ideal gas concept itself.

The molar mass of NH3 is 17.03 g/mol. The molar mass of H2 is 2.0158 g/mol. In a particular reaction, 0.575 g of NH3 forms. What is the mass, in grams, of H2 that must have reacted, to the correct number of significant figures?
0.1
0.102
0.10209
0.1021
Answer : The mass of in grams is 0.102g.
Solution : Given,
Molar mass of = 17.03 g/mole
Molar mass of = 2.0158 g/mole
Given Mass of = 0.575 g
First we have to calculate the moles of .
= = 0.0337 moles
The given balanced equation is,
From the above reaction, we conclude that
2 moles of produced from 3 moles of
then the 0.0337 moles of produces to give moles of
The moles of = 0.0505 moles
The mass of = Moles of × Molar mass of = 0.0505 moles × 2.0158 g/mole = 0.10179 g
The mass of in the correct number of significant figures is 0.102 g.
Answer:
ions and polar molecules
The answer is has a Moh's hardness of 1.
