Volume of 14.00g of nitrogen at 5.64atm and 315k
VikaD [51]

The volume of a 14.00g of nitrogen at 5.64atm and 315K is 4.59L.

<h3>How to calculate volume?</h3>

The volume of an ideal gas can be calculated using the following ideal gas equation formula;

PV = nRT

Where;

  • P = pressure (atm)
  • V = volume (L)
  • n = number of moles
  • R = gas law constant
  • T = temperature

An ideal gas is a hypothetical gas, whose molecules exhibit no interaction, and undergo elastic collision with each other and with the walls of the container.

The number of moles in 14g of nitrogen can be calculated as follows:

moles = 14g ÷ 14g/mol = 1mol

5.64 × V = 1 × 0.0821 × 315

5.64V = 25.86

V = 25.86 ÷ 5.64

V = 4.59L

Therefore, 4.59L is the volume of the gas

What is the molecular formula of a hydrocarbon with m+ = 78?
fiasKO [112]

A molecular formula represents the exact number of atoms present for each element in the compound.  

For carbon atom: \frac{78}{12} = 6\frac{6}{12} ( as molar mass of carbon is 12 g/mol)

Now, 6 carbon atoms are present and rest are hydrogen atoms i.e. 6

Thus, formula becomes C_{6}H_{6} ( C_{x}H_{y})

Now, check for unsaturation:

Degree of unsaturation  = \frac{2x+2-y}{2}

Substitute the value of x and y,

Degree of unsaturation  = \frac{2(6)+2-6}{2}

= \frac{12-4}{2}

= 4 implies one ring and three double bonds.

Thus, formula comes out to be C_{6}H_{6} i.e. benzene ring.

What is the splitting of the signal in the 1H NMR spectrum for the methyl protons of 1-bromo-2-methylpropane?
Arada [10]

Answer:

doublet

Explanation:

Proton MNR is used for the determination of no. of equivalents protons in a molecule

In the molecule, single NMR signal is produced for each set of protons.

Signal splitting is called spin-spin coupling and the splitting of signals depends upon the no. of neighboring proton.

The no. of signal for a proton is equal to n+1, where n is neighboring protons.

In 1-bromo-2-methylpropane, neighboring proton for both methyl protons are one. But the chemical environment of both the methyl protons are different.

Neighboring proton for methyl protons = 1

No. of signal for methyl protons = 1+1 =2

Hence, two doublets will be generated for each set of methyl protons. protons.
