Which phase has a fixed shape? Solid O Gas O Liquid

Four samples of the same unknown gas G are listed in the table below. Rank these samples in increasing order of ideality. That is, select 1 next to the sample of G that will behave least like an ideal gas, and select 4 next to the sample of G that will behave most like an ideal gas. sample pressure (atm) volume (L) temperature (C) How ideal the sample is:       A 30.0 4.0 −10.0 ▼(Choose one) B 20.0 5.0 0.0 ▼(Choose one) C 40.0 4.0 −10.0 ▼(Choose one) D 20.0 6.0 −10.0 ▼(Choose one)       1being least ideal 4 being most ideal

What is the experimental molar mass (that is, calculated from the data given and not taken from the periodic table) of magnesium if 0.0204 grams of magnesium generates 20.54 mL of hydrogen at 24.6 °C with a hydrogen partial pressure of 761.7 torr? Note that the partial pressure of water vapor has already been subtracted from the total pressure. O25.9 g/mol O26.0 g/mol O 24.2 g/mol 23.8 g/mol O 20.9 g/mol
