Caculate the mass of zinc chloride produced from 19.2tones of zinc oxide

The name of your school is not a subject. If this is chemistry, put that in the subject line if you want a chemistry tutor to see your question.
ZnO + 2HCl ==> ZnCl2 + H2O
1. Convert 19.2 tones ZnO to mols. mols = grams/molar mass which means you must convert tones to grams first.
2. Using the coefficients in the balanced equation, convert mols ZnO to mols ZnCl2.
3. Now convert mols ZnCl2 to grams. g = mols x molar mass and convert grams back to tones.(Is that tonnes?)
Note: you can save yourself some time by not convert tonnes to grams in the first place; i.e., in step 1 use 19.2 tonnes directly. Thern in step 3 the answer comes out in tonnes.
