How many carbon atoms are there in a diamond (pure carbon) with a mass of 55 mg ?

kari74 [83]

1 mol of Carbon = 12 grams.
x mol of Carbon = 55 grams

12*x = 1 * 55
x = 55/12
x = 4.583333 mols of carbon

1 mol of anything is 6.02 * 10^23 atoms
4.58333333 mol = x

1/4.5833333 = 6.02 * 10^23/x
x = 4.58333* 6.02*10^23
x = 2.7591 * 10^23 Carbon atoms

A. False. If it is high tide in one place on Earth, the place exactly opposite to it will also have a high tide.

The gravitational attraction of the Moon and the inertia of the oceans cause two tidal bulges on opposite sides of the Earth.

B. True. Cassini used flybys of Venus, Earth and Jupiter as slingshots to reach Saturn.

C. True. The whole solar system moves around the galaxy.

D. True. If a planet’s gravity is not strong enough, the molecules in its atmosphere will have enough kinetic energy to escape into space.

E. False. The mass of an object is constant, but its weight changes according to the gravity of the planet.

F. False. To find the mass of an object, divide its weight by gravity.

$F = mg$ or weight = mass × gravity

∴ Mass = weight/gravity
