(a) What is the volume (in km3 ) of Avogadro’s number of sand grains if each grain is a cube and has sides that are 1.0 mm long? (b) How many kilometers of beaches in length would this cover if the beach averages 100 m in width and 10.0 m in depth? Neglect air spaces between grains.

A cylinder containing 100.9 cubic centimeter of gas at a pressure of 376 kPa when its temperature is 534 K. Given that its temperature is unchanged when the pressure was increased by a factor of 5.9, Determine the new volume of the gas (In cubic centimeter). Note: Your answer must be in cubic centimeter, however, do not include the unit, just enter the magnitude that corresponds to the final volume in cubic centimeter. Round your answer to 2 decimal points Round your answer to 2 decimal points
