Calculate the volume of 0.413 mol of hydrogen gas at a temperature of 20°C and a pressure of 1200 torr.

The volume is 6, 28 liters

Explanation:

The unit of pressure and temperature must be converted. 760 Torr = 1 atm and 0°C=273 K.     20+273=293K

760 Torr---1 atm

1200Torr--x= (1200 Torr x 1 atm)/760 Torr =1,58 atm

PV=nRT V=(nRT)/P

V= (0,413 mol x 0,082 L atm /K mol x 293K)/ 1,58 atm

V=6, 28 L

i dont know the answe

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.
