Grains of fine California beach sand are approximately spheres with an average radius of 50 μm and are made of silicon dioxide, which has a density of 2.5 × 103 kg/m3. What mass of sand grains would have a total surface area (the total area of all the individual spheres) equal to the surface area of a cube 1.2 m on an edge?

a.     A painter uses 4.5 litres of paint to cover a wall with an area of 50 m2. Calculate the average rate of paint coverage in m2/L. b     The painter works for 1.5 hours and then rests for half an hour before completing the painting in another hour. Find the average rate at which the painter paints the wall in m2/h.

One cm3 of gold is 19.32 g. What is the density (ratio of mass to volume) of gold inkg per m3 ?  I know the answer is 19.32x10^3 but can someone tell me the steps to get there?

the average density of an atom is approximately 103 kg/m3. The nucleus of an atom has a radius about 10-5 times that of the entire atom, and contains nearly all the mass of the atom.  What is the approximate density, in kilograms per cubic meter, of a nucleus?

810. A tank has pure water flowing into it at 10 1/min. The contents of the tank are kept thoroughly mixed, and the contents flow out at 10 1/min. Salt is added to the tank at the rate of 0.1 kg/min. Initially, the tank contains 10 kg of salt in 100 1 of water. How much salt is in the tank after 30 minutes?

The radius of Jupiter is about 69.0 × 103 km. The radius of the Sun is about 70.0 × 104 km. How many Jupiter volumes would fit inside the Sun's volume?

The mass of fuel in an airplane must be determined before takeoff. A jet contains 11281 LL of fuel after it has been filled with fuel. What is the mass of the fuel in kilograms if the fuel’s density is 0.767 g/cm3?

A series of five measurements of the mass of a cylinder is made. The results of those measurements are 20.5 g, 20.6 g, 20.4 g, 20.4 g, and 20.5 g. Calculate the mean. Apply the rules of significant figures. O 20.50 g O 20.4 g O 20.48 g O 20.5 g
