You are trying to determine the identity of an unknown metal object using density. You measure the volume by displacement using a graduated cylinder. The initial volume is 14.7 mL, and the final volume is 23.5 mL. The mass is measured using a balance and is determined to be 68.895 g. The calculation you use to find the answer is: $$

Which changes would result in a decrease in the gravitational force btween two objects? check all that apply

You add 800 ml of water at 20c to 800 ml of water at 80c what is the most likely final temperature of the mixture ? a. 100c b. 60c c. 25 c d.50c

Ahypothetical metal has an orthorhombic unit cell for which the a, b, and c lattice parameters are 0.413 nm, 0.665 nm, and 0.876 nm, respectively. (a) if there are 8 atoms per unit cell and the atomic packing factor is 0.536, determine the atomic radius (in nm). (b) if the density is 3.99 g/cm3, calculate the metal's atomic weight (in g/mol).
