Part 1. Determine the molar mass of a 0.314-gram sample of gas having a volume of 1.6 L at 287 K and 0.92 atm. Show your work.

Part 2. Describe the temperature and pressure conditions at which the gas behaves like an ideal gas.

the answer is minerals.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
