BBecause it would lower the amount in the sample causing it to be heated up faster in the process, duh....

The answer is option B

Explanation:

To find the number of moles we must first find the molar mass of the compound after that we use the formula

$n = \frac{m}{M}$

where

n is the number of moles

M is the molar mass

m is the mass

M(Na) = 23 , M(O) = 16 , M(H) = 1

Molar mass ( NaOH ) = 23+ 16 + 1

= 40 g/mol

mass = 65 g

Substitute the values into the above formula and solve

That's

$n = \frac{65}{40} = \frac{13}{8}$

We have the final answer as

1.625 moles

Hope this helps you
