In order to satisfy charge conservation and lepton number conservation the other products must be neutron.
<h3>What is conservation of mass?</h3>
The principle of conservation of mass states that, the sum of the initial mass of reactants must be equal to final mass of the products.
The balanced reaction of radioactive decay of phosphorous shows conservation of mass.
Thus, in order to satisfy charge conservation and lepton number conservation the other products must be neutron.

Answer : The value of 'R' is
Solution : Given,
At STP conditions,
Pressure = 1 atm
Temperature = 273 K
Number of moles = 1 mole
Volume = 22.4 L
Formula used :
where,
R = Gas constant
P = pressure of gas
T = temperature of gas
V = volume of gas
n = number of moles of gas
Now put all the given values in this formula, we get the values of 'R'.
Therefore, the value of 'R' is .
Taking into account the definition of molarity, the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 .
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
Molarity is expressed in units .
In this case, you have:
- number of moles= 30 moles
- volume= 0.80 L
Replacing in the definition of molarity:
Solving:
<u><em>Molarity= 37.5 </em></u><em />
Finally, the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 .
