A: A sample of carbon monoxide occupies 3.93 L at 277.0 K and 692 torr. Find its volume at −21°C and 387 torr. L = ?

B: A sample of chlorine gas is confined in a 7.56−L container at 368 torr and 32.0°C.
How many moles of gas are in the sample?
mol Cl2= ?

Modern weaponry has increased the number of deaths in wars and violent conflicts.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
