Expert Answer
To calculate the number of years it took for the magnesium test specimen to lose 750 grams, we need to consider the density of magnesium and the corrosion rate. Here's the step-by-step calculation:Calculate the volume of the magnesium test specimen: Volume = Length x Width x Thickness Volume = (converting the corrosion rate to mm/yr) Volume = 2273.75 cm³
