Determine the spin-spin splitting pattern and the number of protons that contribute to the integrated 1H NMR signal for the hydrogens in 2-nitropropane. Place the splitting pattern for the hydrogen atom in the targets labeled "Splitting pattern." For example, if the signal has three peaks, place triplet in the target. Place the number of protons that the group contributes to the integrated signal in the targets labeled "Proton number." For example, if the signal is created by two hydrogen atoms on a carbon atom, place two in the target.

See explaination

Explanation:

For the spin-spin splitting pattern and the number of protons that contribute to the integrated 1H NMR signal for the hydrogens in 2-nitropropane. kindly check attachment.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
