Please Provide the Solution for Question 1.11 parts a) and b) with Full Working, Thank you!!

1.11 An industrial storage tank company wants to investigate the rate at which acetic acid corrodes 304 stainless steel before the manufacture of an acetic acid storage tank for a customer. As such, a spherical sample of diameter 6 cm of the 304 stainless steel was completely submerged in acetic acid in a laboratory for one (1) week. Upon removal, the sample weighed 0.9046 kg. a) Using this data, calculate the rate of corrosion of the stainless steel sample. Density of 304 stainless steel = 8.0 g/cm3 Volume of a sphere og 4 = Tp3 Surface area of a sphere = 40r2 r = radius a b) If no resin coating is used on the tank and assuming all other conditions remain constant, determine the life span of the tank before it fails completely if the initial average wall thickness is 7 mm
