Phenol (C6H5OH) is often used as an antiseptic in mouthwashes and throat lozenges. If a mouthwash has a phenol concentration of

amm1812

Answer:

$M=0.16M$

Explanation:

Hello!

In this case, since the molarity is defined as moles of solute divided by liters of solution, since we have phenol with a molar mass of 94.12 g/mol, we can first compute the moles in 1.5 g of phenol:

$n=1.5g*\frac{1mol}{94.12 g}=0.016mol$

Next, since 1000 mL = 1 L, we notice that the volume of the solution is 0.100 L and therefore, the molarity of such solution turns out:

$M=\frac{n}{V}=\frac{0.016mol}{0.100L}\\\\M=0.16M$

Best regards!
