Galvanisation.
The molar mass of zinc is 65,38 g.
65.38(4) g mol-1
The density of pure copper is: 8.94 g/cm^3 The density of pure zinc is: 7.13 g/cm^3
When 4.9 g of zinc is burnt in air, 8.1 g of product is formed
0,356 moles of zinc contain 23,27 g.
Galvanizing usually refers to the coating of steel in zinc by the process of dipping the steel in a bath of molten zinc. This gives a much thicker and more corrosion resistant coating (an average around 175 g/m2) than zinc plating (15 or more microns) which uses an electrolytic process. (These figures come from the related web site linked below) Galvanized steel will vary in density because of several variables: - The type and therefore density of the steel - The thickness of the zinc galvanising layer - The proportion of steel volume to surface area available to the galvanising coating Refer to the related questions on steel and zinc density
Zn(s) + 2HCl ==> ZnCl2(aq) + H2(g)
The molar mass of zinc is 65,38 g.
So for as I know, there are no corrugated steel bars. Only metal sheet (mostly galvanized/ zinc coated) are corrugated. Generally the density of mild steel is taken as 7.85 g/cm3. Irfan
500 g is a mass greater than 200 g.
The answer is 1,15 g zinc.
65.38(4) g mol-1
Zinc- 7.14 g/mL Aluminum- 2.70 g/mL Lead- 11.34 g/mL
A. G. Steel was born in 1858.

500g
Zinc has a density of 7.14 g/cm3 and Aluminums is 2.70 g/cm3 at 300 degrees Kelvin
