Answer:
16.4moles
Explanation:
From Avogadro's hypothesis, 1mole of any substance contains 6.02x10^23 atoms.
This clearly indicates that 1mole of (NH4)3PO4 also contains 6.02x10^23 atoms.
Now, if 1mole of (NH4)3PO4 contains 6.02x10^23 atoms,
Then Xmol of (NH4)3PO4 will contain 9.87X10^24 atoms i.e
Xmol of (NH4)3PO4 = 9.87X10^24/6.02x10^23 = 16.4moles
Answer:
79.7%
Explanation:
Percent yield of reaction is defined as the ratio between theoretical yield of a reaction and actual yield obtained.
In the problem, theoretical yield are 6 moles of KNO₃ and actual yield are 4.78 moles. Thus, percent yield is:
4.78 mol / 6 mol × 100 =<em> 79.7%</em>
<span>Gamma radiation has a shorter wavelength, a higher frequency and higher energy than radio radiation.
Wavelength is inverse to frequency and energy (i.e. higher wavelength means lower frequency and lower energy, and vice versa).</span>
