 Urgent Pls!!! Chemistry Assignment To Be Submited Tomorow. by Simonwal: 9:38pm On Mar 16, 2012 Calculate the volume of hydrogen at stp when 25g of Zinc are added to excess dilute hydrochloric acid at 35degre centgrad and 778mmHg. According to the equation below. Zn(g) +2HCL---; ZnCL2 +H2(g). Molar volume at S.T.P =22.4dm^2, Zn=65, H=1 Re: Urgent Pls!!!

Chemistry Assignment To Be Submited Tomorow. by Simonwal: 5:06am On Mar 17, 2012 Pls i need positive response. Plsss Re: Urgent Pls!!! Chemistry Assignment To Be Submited Tomorow. by owo2390(m): 5:15am On Mar 17, 2012 use pv=nrtv= nrt/pn = number of moles of hydrogen r= 0.08321t = 35+273p = 778mmHg. remember to convert to atmosphereuse the mass of zinc and stoichiometric relationship of zinc and hydrogen to ascertain the number of moles of hydrogen.you have all the info you need to figure the correct answer. good luck 1 Like Re: Urgent Pls!!! Chemistry Assignment To Be Submited Tomorow. by Simonwal: 6:11pm On Mar 17, 2012 @ Owo2390, i couldnt get the value for number of moles of hydrogen. Pls can u help me out Re: Urgent Pls!!! Chemistry Assignment To Be Submited Tomorow. by owo2390(m): 6:34pm On Mar 17, 2012 Divide the Mass of Zinc by its molar mass. Since Zn and H2 have a 1:1 stoichiometric relationship, the moles of Zn are also the moles of H2. Once you do that you should be able to figure out the rest. Re: Urgent Pls!!!
