What is the mass of 1.5E-2 moles of xenon tetra- fluoride?

Answer 1

mass (in grams) = number of moles x molecular weight.

So for 0.015 moles of XeF4, the mass = 0.015 x 207.284 = 3.11 g

Answer 2

To find the mass of 1.5E-2 moles of xenon tetrafluoride (XeF4), you would multiply the number of moles by the molar mass of XeF4. The molar mass of XeF4 is approximately 207.29 g/mol. Therefore, the mass of 1.5E-2 moles of XeF4 would be approximately 3.11 grams.
