Further explanation
</h3>
Given
5.6 g Potassium hydroxide(KOH)
500 ml of solution = 0.5 L
Required
The concentration
Solution
Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution
MW KOH = 39+16+1=56 g/mol
mol solute(KOH) :
= mass : MW KOH
= 5.6 : 56 g/mol
= 0.1
Molarity :
= 0.1 : 0.5
= 0.2 M
Answer:
The mass number of an element is the sum of protons and neutrons.
Hence, 53+66 =119
The mass number of the atom is 119.
15.26 miles of silver is 0.1414689408 grams
