I know water will change the shape to match the container its in if that is your question
Answer:
74,67 gr/mol
Explanation:
At STP 1 mole of an ideal gas has volume of 22,4 L. Since we know the volume of the gas we can find the number of moles of the gas. (300 mL=0,3 L)
n=0,3L/22,4 L=0,01339 mol
Since we know weight of the gas as 1 g, we can find the molecular weight as;
MW=1 g/0,01339 mol =74,67 gr/mol
2x 6.022x10^23= 1.204x10^24
It is the darmstadtium element that has the electron configuration above and the atomic number of 110
