The molarity is count by dividing the mole of the solute within 1 liter of solvent. In this case, the KNO3 is 16.8g with 101.11 g/mol molar mass. Then we need to find the mol first. The calculation would be: 16.8g / (101.11g/mol)= 0.0166 mol.
Then the molarity would be: 0.0166mol/ 0.3l= 0.0498= 0.0553 M
I can’t see the choices can you take another picture of this assignment please so i can help you
Answer:
A and B
Explanation:
the other two make no sense at all
The gas particles squeeze closer together
It is the electron sharing.
electronegative element + electronegative element
exemple :
O₂ , H₂
hope this helps!
