Question

The number of atoms in 32 gram of so2 is approximately

Answer 1

Explanation:

Given Mass=32g

SO2=32+16*2=64g

Therefore

we know that

No. of atoms=No. of Moles*NA

No. of moles =Given mass /molar Mass

No. of Moles=32/64=1/2=0.5 moles

Therefore

No. of atoms=0.5*NA=0.5*6.022*10²³

=3.011*10²³ atoms

Hope that helps

Answer 2

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles SO2, or 64.0638 grams.
