Thank you for the opportunity to help you with your question!

KCL molar mass=74.55G/MOL

0.202 mols contain=0.202/1*74.55g/mol=15.06grams

1 mole=22.4 litres

7.98l=7.98/22.4=0.3563 moles

molarity= 0.3563

Please let me know if you need any clarification. I'm always happy to answer your questions.
