Question

What is the number of miles in 49.8 mL of 1.0 M NaOH

Answer 1

To find the number of miles of NaOH, simply convert 49.80 ml into L, and then multiply it to the molar concentration of NaOH, so in this case the number of moles would be 0.04980 moles of NaOH. This would also equal the moles of H2O, as there is a 1:1 ratio between moles of base and moles of H2O.

Answer 2

Answer:

$0.0498~mol~NaOH$

Explanation:

The have to start with the molarity equation:

$M=\frac{mol}{L}$

Then we have to solve for "mol":

$mol=~M*L$

As we can see in the equation, we have to convert from mL to L as a first step:

$49.8~mL~\frac{1~L}{1000~mL}~=~0.0498~L$

Then we have to plug this value into the mol equation:

$mol=~1.0M*0.0498~L$

$mol=0.0498$
