Answer:109.5g HCL
Explanation: 1st get the GFM of H2S, which is 34g/mol, and divide 57g by it. You get the moles for H2S: 1.7. Put what you have over what you want (have/want) equal to what other chemical you want like this:
8H2S/1.7H2S = 16HCl/X
Solve for it like an algebra equation
8x = 27.2 27.2/8 = 3.4molHCl
Round to sig figs
3molHCl
Multiple by HCL GFM (36.5g/mol)
3mol x 36.5g/mol
109.5gHCl
