Can you please help me with these two qustions. Thank you.
The density of an unknown spherically shaped material was measured to be 6.00 times 10^2 kg/m^3 at 23.0 degree C. If the diameter of this unknown material was 4.50 mm, what is the mass (in grams) of the material? A gold bar has the following dimensions: 3.90 cm by 2.20 cm by 0.13 cm. If gold has a density of 19.3 g/cm^3, determine the mass of that gold bar.
