Answer:

648.12g

Explanation:

First, we need to find the molar mass of ammonium sulphate (NH4)2SO4. This can be achieved by:

Molar Mass of (NH4)2SO4 = 2(14+4)+32+(4x16) = 132g/mol

Mass of (NH4)2SO4 = 4.91x132 = 648.12g

Does the number of electrons reaching the detector increase or decrease as you change the frequency?
velikii [3]
If you increase the frequency, the photon will have more energy and can therefore transfer more electrons to the other side. As such, you will have an increased current.

If you found carbon 13 atom, you would know that
bearhunter [10]
The Options are as follow,

<span>a. it has 13 protons                  c. it has 13 neutrons                      </span>

<span>b. it has 13 electrons               d. it has 7 neutrons</span>


Answer:

             Option-d is the correct answer.


Explanation:

             As we know that C-13 has a atomic mass of 13. Also, atomic mass is given as,


<span>                 Atomic Mass  =  # of Protons  +  # of Neutrons   --- (1)</span>


Since;

          Atomic Mass  =  13

And,

          # of protons  =  6 (as number of protons  =  atomic number)


Putting values in equation 1,


                               13  =  6  -  # of Neutrons


Solving for Number of Neutrons,


                               # of Neutrons  =  13  -  6


                               # of Neutrons  =  7
