Explanation:
1.
Sodium, or Na, is 57.47% of the composition,
Hydrogen, or H, is 2.520% of the composition,
and Oxygen, or O, is 40.001% of the composition.
This is because mass% = mass/total mass x 100%.
2. For every 1 mole of C6H12O6, you need 6 moles of water. Multiply the 5.2 moles you are trying to make by the 6 moles of water you need, and you will need 31.2 moles.
3. x = 7.2 x 4 / 2 = 14.4 mol
Answer:
The pH of the buffer is 7.0 and this pH is not useful to pH 7.0
Explanation:
The pH of a buffer is obtained by using H-H equation:
pH = pKa + log [A⁻] / [HA]
<em>Where pH is the pH of the buffer</em>
<em>The pKa of acetic acid is 4.74.</em>
<em>[A⁻] could be taken as moles of sodium acetate (14.59g * (1mol / 82g) = 0.1779 moles</em>
<em>[HA] are the moles of acetic acid (0.060g * (1mol / 60g) = 0.001moles</em>
<em />
Replacing:
pH = 4.74 + log [0.1779mol] / [0.001mol]
<em>pH = 6.99 ≈ 7.0</em>
<em />
The pH of the buffer is 7.0
But the buffer is not useful to pH = 7.0 because a buffer works between pKa±1 (For acetic acid: 3.74 - 5.74). As pH 7.0 is out of this interval,
this pH is not useful to pH 7.0

Magnesium potassium phosphate hexahydrate and a number of its deuterated counterparts were studied for their Fourier transform infrared and Raman spectra. By contrasting the spectra obtained at the boiling point of liquid nitrogen with those obtained at ambient temperature and by examining the spectra of a succession of partially deuterated MgKPO4
<h3>What is Infrared and raman spectroscopy ?</h3>
Raman and infrared spectroscopy both investigate how radiation interacts with molecular vibrations, but they do so in different ways depending on how the photon energy is delivered to the molecule by altering its vibrational state.
- While IR spectroscopy depends on a change in the dipole moment, Raman spectroscopy depends on a change in the polarizability of a molecule. In contrast to IR spectroscopy, which measures the absolute frequencies at which a sample absorbs light, Raman spectroscopy measures the relative frequencies at which a sample scatters light.
