Answer: The volume of an ideal gas will triple in value if the pressure is reduced to one-third of its initial value
Explanation:
We can determine this from the gas laws. Using Boyle's law, which states that "the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature"
Mathematically, P ∝ (1/V)
Since P ∝ (1/V), we can then write that
P = k(1/V)
Where P is the pressure, V is the volume and k is the proportionality constant
PV = k
We can then write that
P1V1 = P2V2 = P3V3 = ...
Hence, P1V1 = P2V2
Where P1 is the initial pressure of the gas
P2 is the final pressure of the gas
V1 is the initial volume of the gas
and V2 is the final volume of the gas
From the question, we want to determine what will make the new volume be thrice the initial volume.
Hence,
P1 = P
V1 = V
P2= ??
V2 = 3V
Therefore,
P × V = P2 × (3V)
P2 = PV/3V
P2 = P/3 = 1/3(P)
This means the volume of an ideal gas will triple in value if the pressure is reduced to one-third of its initial value

In accordance to Quantum Mechanical model of an atom:
- The Principle Quantum number (n) gives the description of the shell of an electron and the energy level of an electron in an atom.
- The angular momentum also referred to as Azimuthal Quantum number (l) gives the description of the shape of the orbitals and helps in determination of angular momentum magnitude.
- The magnetic quantum number () describes the energy levels or the number of orbitals contained in a subshell and the way these are oriented within.
- The spin quantum no. () determines the elelctron spin's direction which may be () or ().
Answer:
13.0186g/mole
63.0326g/mole
Explanation:
Given parameters;
Compounds - CH
CH₃O₃
To solve this problem, let us delve a bit into molar mass of a substance;
The molar mass of a substance (atom or molecule or compound) is the mass in grams of one mole of the substance.
Simply add the component atomic masses to find this number;
Atomic mass of Carbon = 12.0107g/mole
Hydrogen = 1.0079g/mole
Oxygen = 15.9994g/mole
Molar mass of CH = 12.0107 + 1.0079 = 13.0186g/mole
Molar mass of CH₃O₃ = 12.0107 + 3(1.0079) + 3( 15.9994) = 63.0326g/mole
