Indicate your specific subject in the "School Subject" box, so those with expertise in the area will respond to the question.
Your subject looks like chemistry to me. If you need a tutor to study national school, that's another matter.
H2SO4 + Cu ==> no reaction in the cold.
H2SO4 + Fe ==> FeSO4 + H2
4.48 L x (1 mol/24 L) = mols H2.
Using the coefficients in the balanced equation to convert mols H2 to mols Fe.
grams Fe = mols Fe x atomic mass Fe
Subtract from initial sample to find mass Cu
H2SO4 + Fe ==> FeSO4 + H2
4.48 L x (1 mol/24 L) = mols H2.
Using the coefficients in the balanced equation to convert mols H2 to mols Fe.
grams Fe = mols Fe x atomic mass Fe
Subtract from initial sample to find mass Cu

I have this question on my book (CRDP Lebanon) and I randomly found this on the internet lol.
No response just I hate chem
20 5.5 g of bronze (an alloy of copper and tin, Cu-Sn) containing 23 % of Sn are dipped in an excess of HCI. a) Write the balanced equation of the occur- ring reaction. b) What is the volume of H2 evolved when the molar volume of the gas is 24 L.mol? c) What is the final concentration of Snt ions produced if the volume of the solution is 200 mL?
