What volume will 0.416 g of krypton gas occupy at STP?

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

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
