How many grams are in 882 μg? & the density of gold is 19.3 g/cm3.?
answer the following:
a. what is the volume, in cubic centimeters, of a sample of gold with mass 0.715 kg?
b. if this sample of gold is a cube, how long is each edge in centimeters?

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c
