Calculate the mass (in kg) of 4.87 X 10^25 atoms of Zn?

1 mole = 6.022 x 10²³ atoms.

The atomic mass can be found on the periodic table and Zinc is element number 30.

Expert Solution

This deal with the mole concept and molar mass. One mole is known as Avogadro's number and it equals to 6.022 x 10²³. Mass is always express in grams. The atomic mass of Zinc is 65.4g.

The 65.4g is multiply to the 4.87 to get a value of 318.498.

The mass in kilogram of 4.87 x 10²⁵ atoms of Zn is 5.29 kg.

Two children, A (mass 25 kg ) and B (mass 50 kg ), are playing on a merry-go-round (which you can assume is a solid disk with mass 225 kg and radius 1.5m). Assume that any friction on the axle of the merry-go-round is negligible. (A) A starts spinning the merry-go-round, giving it an angular velocity of 7 rad/s, then she stops pushing it. B runs with a speed of 6 m/s directly toward the center of the merry-go-round....

An electron (mass m1 = 9.11 x 10-31 kg) and a proton (mass m2 = 1.67 x10-27 kg) attract each other via an electrical force. Suppose that an electron and a proton are released from rest with an initial separation d = 2.40 x 10-6 m. When their separation has decreased to 0.510 x 10-6 m, what is the ratio of (a) the electron's linear momentum magnitude to the proton's linear momentum magnitude, (b) the electron's speed to the proton's...

A package of mass 50 kg sits on an airless asteroid of mass 1.25 x 10^13 kg and radius 1000 m. We want to launch the package straight up so that it reaches a maximum distance of 4000 m from the center of the asteroid, where it will be picked up by a waiting ship before it can fall back down. We have a powerful spring whose stiffness is 1000 N/m. How much must we compress the spring to release...
