Answer: 633.6 g of can be produced from the decomposition of 4.8 moles of
Explanation:
The balanced chemical equation for decomposition of is :
According to stoichiometry :
1 mole of produce = 3 moles of
Thus 4.8 moles of will rproduce=
of
Mass of
Thus 633.6 g of can be produced from the decomposition of 4.8 moles of
<u>Answer:</u> The mass defect for the formation of phosphorus-31 is 0.27399
<u>Explanation:</u>
Mass defect is defined as the difference in the mass of an isotope and its mass number.
The equation used to calculate mass defect follows:
where,
= number of protons
= mass of one proton
= number of neutrons
= mass of one neutron
M = mass number of element
We are given:
An isotope of phosphorus which is
Number of protons = atomic number = 15
Number of neutrons = Mass number - atomic number = 31 - 15 = 16
Mass of proton = 1.00728 amu
Mass of neutron = 1.00866 amu
Mass number of phosphorus = 30.973765 amu
Putting values in above equation, we get:
Hence, the mass defect for the formation of phosphorus-31 is 0.27399
