151 mL is the correct answer to the given question .

Explanation:

We know that

PV =n RT

Where P =pressure ,V=volume and T=Temperature

Given

P=95.9 kPa.

V= $180 * 10 ^{-3}$

R=25/3

T=273 + 35 =308k

Putting these value into the equation we get

$95.9\ * 180\ *\ 10^{-3} \ =\ n * \frac{25}{3} * 308$

n= $6.72 * 10^{-3}$

Now using the equation

$n= \ \frac{V}{22.4}$

$6.72 * 10^{-3} =\frac{V}{22.4}\\ V\ =\ 150.6mL$

This can be written as 151mL
