If the atomic radius (r) of aluminum is 0.143 nm, calculate the volume of its unit cell in cubic meters. use the following formula for the volume of its unit cell volume = 16r2 report your results with appropriate unit, significant figures, and scientific notation. b) the structural damage due to explosion/accident from a chemical plant is calculated using a probability equation: y = -23.8 +2.92 x in(p) where p is the peak overpressure in n/m? if y= 5.00, find the value of the peak overpressure (p) in its derived unit. apply the significant figure(s) rule for your result.
