Question

How many miles of SO2 have same masses 3 moles of oxygen​

Answer 1

Answer:

Conclusion: 0.75 moles of have same mass as 3 moles of oxygen.

Answer 2

Given:

Two chemicals = SO2 and O

Number of moles of oxygen = 3

To find:

Number of moles of SO2 in 3 moles of Oxygen

Calculation:

Step 1:

Calculation of the molar mass of given chemicals

Molar mass of SO2  = 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  SO2= 64g

3 mole of oxygen = 16×3 = 48g

Step 3:

Calculation of number of moles of SO2  with same mass of 3 moles of oxygen

64 g of  SO2  = 1 mole

∴ 48 g of SO2 = x

On cross multiplication:

x × 64 = 1 × 48

x =  1×48/64

x =   48/64

x = 0.75 moles

Conclusion:

0.75 moles of   have same mass as 3 moles of oxygen.
