Divide this problem in to two steps: 1. Convert millimoles to moles. 2. Convert moles to grams.
1.
2.65 mlmol x 1mol/1000mlmol=.00265mol
2.
.00265mol x 32.065g/1 mol=.0850g S
Let me know if you need more explanation on why I used the conversions that I did.

Answer:
50. 5mol
Explanation:
The mass of Zinc required = 3.30 kg = 3300 grams
The relation between moles and mass is:
Atomic mass of Zinc = 65.38g/mol
The answer to three significant figures will be 50.5 mol
Acids react with most metals to form a salt and hydrogen gas. ... For example, zinc metal reacts with hydrochloric acid producing zinc chloride and hydrogen gas. \[\ce{Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)}\] Bases react with certain metals like zinc or aluminum for example to also produce hydrogen gas.
