4. Check dimensions of the formula and verify that the formula is dimensionaly correct : V=gh +e v - velocity; g – gravity acceleration; h - size; p - preassure; p - density

One mole of Gold (Au) atom has a mass of 197 g. We know that the density of gold is 19.30 g/cm3 in room temperature. Using those numbers, answer the following questions: a) What is the mass of a single gold atom in kg? b) Assume that gold atoms sit in a perfect cubic crystal structure. Estimate the distance between two gold atoms in meters.   c) If we have a gold cube of 6 cm on each side, how many atoms can we fit along the edge of each side of the cube?  d) What would be the mass, in kilograms, of the gold cube we discussed in part (c) (measuring 6 cm on each side)?

1. Which statement is true for any density curve?  a) It is symmetric. b) The total area under the curve is one. c) It must either steadily rise or steadily fall, since it cannot do both. d) It has all of these properties.

Please help. This problem involves finding the radius and volume of a platinum atom using its density. Thank you.
