Answer:
228.1 m
Explanation:
Area of the magnesium strip = 0.104m * 2.52 * 10^-3 = 2.62 * 10^-4 m^2
Density of Magnesium strip = 1.74g/cm3
Mass of magnesium strip = 0.104 g
But
density = mass/ area * thickness
density * area * thickness = mass
thickness = mass/density * area
thickness = 0.104 g/2.62 * 10^-4 * 1.74
thickness = 0.104 g/ 4.56 * 10^-4
thickness = 228.1 m
