How many moles of solute would be needed to form two liters of a one molar
1 answer:
Answer:
2 moles of solute.
Explanation:
Molarity is defined as number of moles of solute present in one litre of solution.
Hence one molar solution of NaCl means 1 mole of NaCl is present in 1 litre of solution.
Molarity =
For 1 litre of solution 1 mole of solute is required to make a one molar solution.
Hence for 2 litres of solution we require 2 moles of solute to keep it one molar.

Answer:
5. Selenium, because it does not have a stable, half-filled p subshell and adding an electron does not decrease its stability.
Explanation:
Electron affinity is the amount of energy released when an isolated gaseous atom accepts electron to form the corresponding anion.
Selenium:-
The electronic configuration of the element is:-
Arsenic:-
The electronic configuration of the element is:-
The 4p orbital in case of arsenic is half filled which makes the element having more stability as compared to selenium.
Thus, selenium has higher electron affinity because adding electron does not decrease the stability as in case of arsenic.
