    Hi lore_lime! Generally the posters on this site aren't going to answer homework or lab questions for you. What they will do is to review your work, and help where you are stuck so you can work the problem on your own. If you share what you have done so far, you are WAY more likely to get some help. Hope this is helpful in your use of the site.

    First do the equation. Zn +? HCl=H2 +? Once you do that you can figure out moles. You will also need to make adjustments using Boyle's gas Law and Charles' Law..
