A typical gold bar has dimensions of 82 mm long, 45 mm wide and 16 mm deep. The current price for gold is $1,368 per ounce (mass).

a. What is the total surface area, in square inches, of the gold bar?
b. Determine how many mL of gold were used to make the gold bar?
c. If the density of gold is 19.3 g/cm^3, what would be the cost of this gold bar?

Please show all the work.

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
