Question

A cough syrup contains 0.011 M dextromethorphan. How many moles of the cough suppressant are in one teaspoon (5.0 mL) of the cough syrup?​

Answer 1

Dear Priyanshi,

◆ Answer -

Moles of cough suppressant = 5.5×10^-5 moles

● Explanation -

# Given -

C = 0.011 M

V = 5 ml = 5×10^-3 L

# Solution -

Molarity of the solution is calculated as -

Molarity = moles of solute / volume of solution

Moles of solute = Molarity × volume of solution

Moles of solute = 0.011 × 5 × 10^-3

Moles of solute = 5.5×10^-5 moles

Therefore, one teaspoon of the cough syrup will contain 5.5×10^-5 mol of dextromethorphan.

Thanks dear...
