Find the ratio of the volume divided by the
Nataly [62]

From the pair of values given, the ratio of the volume to the temperature for the first data pair is, 0.0026 cm³/K

<h3>What is a Ratio?</h3>

A ratio is a comparison between two quantities showing how much one quantity differs from another.

From the data given, the first data pair is as follows ;

  • Temperature = 276 K
  • Volume = 0.72 cm³

Ratio of volume to temperature = volume / temperature

Ratio = 0.72 / 276

Ratio = 0.002608 cm³/K

The significant figure's rule for division is the least number of significant figures used in the operation.

The least significant figure of the values given is 2.

Therefore, the ratio of the volume to the temperature for the first data pair is 0.0026 cm³/K

How many peaks are in the proton spin decoupled 13c nmr spectrum of 1,3,5-trinitrobenzene?
Natalka [10]

There are 2  peaks are in the proton spin decoupled 13C NMR spectrum of 1,3,5-trinitrobenzene .

The 13C NMR spectrum give the peak which is directly about the carbon skeleton not just the proton attached to it  . The number of signals tell us how many different carbons or set of equivalent carbons . The splitting of a signal tells us how many hydrogens  are attached to each carbon.

In 1,3,5-trinitrobenzene molecule , there are 2  peaks are in the proton spin decoupled 13C NMR spectrum three carbon give one signal and another three carbon give another one signal .
