Question

from the reaction. cu + 2h2so4 → cuso. + 2h2o + so, calculate the mass of sulphuric acid is required to react with 80 g of copper metal? [atomic mass cu = 63.5; h= 1; s = 32: 0= 16]​

Answer 1

Answer:

247g of H2SO4

Explanation:

Standard Reaction:

Cu + 2H2SO4 → CuSO4 + SO2 + 2H2O

Cu = 63.5g 2H2SO4 = 2*98 = 196g

Now, from the Standard Reaction,

63.5g Cu react with 196g H2SO4

Therefore, for 80g of Cu:

(80*196)/63.5 = 247g of H2SO4
