Answer:
Because of the less reactivity of copper.
Explanation:
As well as being resistant to the elements and thereby less likely to be affected by rainfall, hail, and mildew than other types of roofing, copper is also one of the most fireproof materials available. Copper is also highly resistant to thermal changes and thereby doesn't deteriorate quickly.
Magnesium would also corrode PDQ. Magnesium sheeting would also pose an unacceptably high fire hazard.

Answer:
Molarity = 3 M
Explanation:
Given data:
Molarity of solution = ?
Mass of sodium chloride = 87.75 g
Volume of solution = 500 mL (0.5 L)
Solution:
Number of moles = mass/ molar mass
Number of moles = 87.75 g/ 58.44 g/mol
Number of moles = 1.5 mol
Molarity:
Molarity = number of moles / volume in litter
Molarity = 1.5 mol / 0.5 L
Molarity = 3 M
