Iridium is essentially tied with osmium for the distinction of being called the "densest element" with a density of 22.5 g/cm³. What would be the mass in pounds of a 1.0 ft * .0 ft * 1.0 ft cube of iridium (1 lb = 453.6 g) A) 1.5 lb B) 5.2 lb C) 6.20 lb D) 1.4 * 10³ lb E) 6.4 * 10⁵ lb

To find the mass in pounds of a 1.0 ft³ cube of iridium, first convert the volume to cm³ (since density is given in g/cm³). 1 ft³ = (30.48 cm)³ = 28316.8466 cm³. Multiply this by the density of iridium (22.5 g/cm³) to get the mass in grams: 28316.8466 cm³ * 22.5 g/cm³ = 637629.05 g. Convert grams to pounds by dividing by 453.6 g/lb: 637629.05 g / 453.6 g/lb ≈ 1405.8 lb, which is 1.4 * 10^3 lb.
