Step 1

AT STP that is standard temperature and pressure,

T=273 K

P = 1 atm

The ideal gas law is represented by the equation (1) in which in which P is the pressure of hydrogen sulfite, T is the kelvin temperature of hydrogen sulfite, n is the number of moles of hydrogen sulfite, V is the of hydrogen sulphite and R is the molar gas constant.

Step 2

The relation between mL and L is shown below:

1 mL = 0.001 L

Thus,

150 mL = 0.15 L

Rearrange equation (1) for n and substi...
