Arigid, 2.50 l bottle contains 0.458 mol he. the pressure of the gas inside the bottle is 1.83 atm. if 0.713 mol ar is added to the bottle and the pressure increases to 2.05 atm, what is the change in temperature of the gas mixture? use the correct number of significant digits. the initial temperature of the gas is

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

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
