To convert atmospheres (atm) to pascals (Pa), you need to multiply the pressure in atmospheres by the conversion factor 101325 Pa/atm.

Therefore, 0.9831 atm is equal to:

0.9831 atm × (101325 Pa / 1 atm)

= 9.964 × 10^4 Pa

Converting pascals to atmospheres is done by dividing the pressure in pascals by the conversion factor 101325 Pa/atm. Therefore, the provided value of 9.964 × 10^4 Pa is equivalent to:

(9.964 × 10^4) Pa / (101325 Pa / 1 atm)

≈ 0.9831 atm

So, 0.9831 atm is approximately equal to 9.964 × 10^4 Pa.
