Answer:

Explanation:

Pressure P = 895 mm of Hg

895/760 atm

= 1.1776 atm

Temperature T = 35 + 273 = 308 K

volume V = 9.55 mL

9.55 x 10⁻³ L

Value of R = .082 Litre-atm/mol.K

Putting the value in gas equation

[tex]\frac{PV}{RT} =n[/tex]  , n is no of moles of gas.

[tex]\frac{1.1776\times9.55\times10^{-3}}{.082\times308} =n[/tex]

= .4453 x 10⁻³ moles .
