Concepts and reason
This problem is based on the concept of Nuclear magnetic resonance which involves the absorption of radiations in the radio frequency region. This spectroscopy is generally used for the determination of the type and number of protons present in a molecule.
Fundamentals
A spinning charge creates a magnetic field and therefore behaves as a tiny magnet . The spinning nuclei generate a magnetic field on exposure to an external magnetic field . If an external magnetic field is applied , spinning nuclei can get oriented in two ways:
The magnetic field due to nuclei is in the same direction as the external field. In this case, the nuclei are said to be in a low energy spin state.
The magnetic field due to nuclei is in the opposite direction as the external magnetic field. In this case, the nuclei are said to be in high -energy spin state.

Answer:
2 L is the new volume
Explanation:
We can apply the Ideal Gases Law to solve the problem.
At STP, we kwow that 1 mol of gas occupy a volume of 22.4 L
Then, how many moles do we have in 1 L?
Let's do it by a rule of three:
(1L . 1 mol) / 22.4L = 0.0446 moles
These moles are at 1 atm and 273 K of temperature, so let's change our conditions.
P . V = n . R .T
1 atm . V = 0.0446 mol . 0.082 L.atm/mol K . 546 K
V = 2 L
If we pay attention, we can notice that, if we double temperature, we double the volume.
Janice’s yard was probably not exposed to as much sun and heat as the yard across the street
Answer:
Mn(NO3)3 Molar mass = (54.93) + (3 x 14) + (9 x 16) = 240.93g/mol
Total number of Oxygen atoms in formula = 9
Total mass of oxygen atoms theoretically in the formula = 9x16 = 144g/mol
Oxygen's percentage composition:
(144/240.93) x 100 = 59.7% of the compound is oxygen
