V =L

Can you help me with these 3 questions, please?

Answer 1

@ Amount of Hgo = 6.4869 - 6.48x100mg Molar mass of Hego = 216.59 g/mol son number of moles of thingos 216.59 gimul = 29,92 mol Now, given egen so, from 2 motes at T 29,92 , 2 2Hgo () 2Hryle) + O2(g) so from 2 mutes of Hoo, I mole of a produce & so for 2.92!! 14.96 more of q s P = 1.064 atm, T: 21.1°C: (273121-1) = 294.1K 29.92 ? wanRT 14.9% mfl x0022_Lethembt-lyf! x 294.1K VED 1.064 aka = 339.08L su volume of a 2 339.08L M B. 1 we know, p= PM P= 1.00f at t = 27.5'c - (273+27'5 c) : 300.5k M = 10x 120191 g/mol Brown e 1.006affn X 480pogleA 1209140mm - Doe2 leth nghit kà x 300-5 XC = BorZX geleden -=4.944 g/L
