Chapter 2, Problem 80QRT

Students have asked these similar questions

(a) Atoms are very small compared to objects on the macroscopic scale. The radius of a nickel atom is 125 pm. What is this value in meters and in centimeters? cm -23 (b) The mass of a single nickel atom is 9.75×10 g. Suppose enough Ni atoms were lined up like beads on a string to span a distance of 31.3 cm (12 inches). How many atoms would be required? atoms What mass in grams of Ni would be used? Could you weigh out this amount of nickel using a typical laboratory balance? (c) Taking the density of nickel metal to be 8.91 g/cm, calculate the mass of metal needed to form a piece of Ni wire with the same length as the distance in b, but with a diameter of 1.00 mm. Hint: The volume of a cylinder is n times its radius squared times its height. (V = nr h) How many nickel atoms does this represent? atoms

(11) Name this substance. (c) An unknown atom has 20 neutrons. Its mass is 6.138 x10-23 g. (i) (ii) Determine the chemical symbol of the atom. Show all your calculations. Name this substance.

Calculate (a) the number of atoms in 1.05 × 10−6 mole of helium and (b) the number of moles of helium that contains 2.33 × 1021 atoms.
