Answer:

Empirical formulas can be determined from the percent composition of a compound. In order to determine its molecular formula, it is necessary to know the molar mass of the compound. Chemists use an instrument called a mass spectrometer to determine the molar mass of compounds.

hope this helps :3

Calculate the density of a cube of iron that measures 3.50cm, 0.755 cm, 2.25cm on each side and weighs 47.0g?
laila [671]

Answer: 7.90 g/cm^3

Explanation:

Density = Mass / Volume

The first step is to find the volume by multiplying the three measures of the cube that have been provided.

3.50 x 0.755 x 2.25 = 5.95 cm^3

Now we can plug the numbers into our equation.

Density = 47.0g / 5.95 cm^3

Density = 7.90 g/cm^3

Aniline is more basic than cyclohexylamine because: (A) electrons on the aniline nitrogen are somewhat delocalized into the arom
Nady [450]

Answer:

The correct answer is A electron on the aniline nitrogen are somehow delocalized to the aromatic ring.

Explanation:

The structure of aniline contain double bonds and lone pair of electron in the nitrogen atom of -NH2 group that is attached to the benzene ring.

  The electron pair present in the nitrogen atom of -NH3 group of aniline undergo delocalization with the aromatic ring of benzene resulting in the formation of resonance hybrid that increases the ability of nitrogen atom of -NH2 group of aniline to easily donate that lone pair of electron.

 ON the other hand the resonance stabilization cannot be possible with the cyclohexylamine ring as it is saturated.
