Calculate the number of grams

Question

Calculate the number of grams of xenon in 5.697g of the compound xenon tetrafluoride.

Answer 1

XeF₄ → Xe + 2F₂

Xenon tetrafluoride = XeF₄

molar mass = Xe = 1 x 131.3 = 131.3

F = 4 x 19 = + 76

207.3 g/mol

5.697 g XeF₄ x 1mol XeF₄ x 1 mol Xe x 131.3 g Xe = 3.61 g Xe

207.3 g XeF₄ 1 mole XeF₄ 1 mol Xe
