Drug A is an nasal drops contains 0.05%w/v benzalkonium chloride. What volume of drug A nasal drops would contain 101 mg of benzalkonium chloride.
Homework Answers
Ans :
w/v% = ( mass of solute / volume of solution) x 100
putting values :
0.05 = ( 101 / V) x 100
V = 202000 mL
or 202000 / 1000
= 202 Litres
So 202 litres of drug A nasal drops would contain 101 mg of benzalkonium chloride.
