Question

calculation the molarity of HNO3 Solution prepared by dissolving 6.022×10^molecules in 10L solution.(MW HNO3=63g/mol)​

Answer 1

molecule of HNO3=6.022×10^23

moles

= mass/ molar mass= molecule of HNO3/ Na

mass=6.022×10^23×63/6.022×10^23

mass=63g

moles= 1

Molarity

= moles HNO3/ vol soln

=1/10

=0.1M
