Answer:
0.11L
Explanation:
To get the volume of krypton at stp, we must cover the mass given in the question to mole. This is illustrated below
Mass of krypton = 0.416g
MM of krypton = 84g/mol
Number of mole = Mass /Molar Mass
Number of mole of krypton = 0.416/84 = 0.00495mol
1mole of a substance occupies 22.4L at stp this implies that 1mole of krypton also occupy 22.4L at stp. Therefore,
0.00495mol of krypton will occupy = 0.00495 x 22.4L = 0.11L
