Question

number of mole in 128g of So2 will be​

Answer 1

Correct Question

Find the number of moles in 128g of SO2.

Answer

• Given Mass of SO2,m = 128g

We Know that,

Mass of Sulphur = 32g

Mass of Oxygen = 16g

Now,

• Molar Mass of SO,w = 32 + (2×16) = 64g

Let there be n no.of moles in 128g of SO2

Mol - Weight relationship is given by:

$\huge{\underline{\boxed{\sf{n = \frac{m}{w} }}}}$

Thus,

$\sf{n = \frac{128g}{64g} } \\ \ \\ \rightarrow \: \boxed{ \sf{n = 2}}$

Thus,there are 2 moles in 128g of SO2
