6) How many moles of SO2, have same mass as 3 moles of oxygen? |
|
Answer» Answer: Given: TWO chemicals = and O Number of moles of OXYGEN = 3 To find: Number of moles of in 3 moles of Oxygen Calculation: Step 1: Calculation of the molar mass of given chemicals Molar mass of = 1(S) + 2(O) = 1 (32) + 2 (16) = 32+32 = 64g. Molar mass of Oxygen = 16g Step 2: Calculation of 1 moles of the given substance 1 mole of substance = Molar mass of the substance. ∴ 1 mole of = 64g 3 mole of oxygen = 16×3 = 48g Step 3: Calculation of number of moles of with same mass of 3 moles of oxygen 64 g of = 1 mole ∴ 48 g of = x On CROSS multiplication: x × 64 = 1 × 48 x = x = x = 0.75 moles Conclusion: 0.75 moles of have same mass as 3 moles of oxygen.
