A bottle of soda is pressurized to 3.75 atm. At this pressure, carbon dioxide has a solubility of 0.65 g per 100 g H2O. When the bottle is opened, the partial pressure of CO2 falls to 0.30 torr. What is the solubility of CO2 in the soda at this pressure

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.
