Answer 1

(A) By Ideal gas law, pVan RT Here, P= 1.29 bar = 1 . 2 atm = 1.27 atm na moto mass es so = 0-3995 mol 1:013 Rs 0.0821 Lammolalk-I, T=494K vs. 0.3975 m01X0.0821 bin ton x 434K 1.27 am ? :| = 12.7.11 (B) na mors mess. .* *3.975 mol 3 VE 3.995 mol x 0.0821 29 mm x 494 . 1.27 am so, volume would be greader for helium gasi' .
