Question

calculate the mass of sulfur dioxide produced by burning 16 g of sulfur in excess of oxygen in contact process (average atomic mass : s =32 u , O = 16 u)

Answer 1

Answer:

The mass of sulfur dioxide is 48 unit

Step-by-step explanation:

S+ O2= SO2

1 mole of sulfur and 1 mole of oxygen reacts and make one mole of sulfur dioxide.

As given,  atomic mass : s=32 unit  o= 16 unit

therefore the atomic mass of so2= 32+(16*2)

                                                        = 64 unit

now if we say that we will use 16g of sulfur

then the atomic mass of so2= 16+(16*2)

                                                        = 48 unit
