How many molecules are present in 4.9g of H2SO4?

1.	How many molecules are present in 4.9g of H2SO4?
Answer» For H₂SO₄ one mole is equal to 98 grams. Therefore, calculating the number of moles for 4.9 grams n = 4.9/98 = 0.05 moles So, for 0.05 moles the number of gram molecules is 0.05-gram molecules. Hence, the number of gram molecules is 0.05.

Answer»

For H₂SO₄ one mole is equal to 98 grams.

Therefore, calculating the number of moles for 4.9 grams

n = 4.9/98 = 0.05 moles

So, for 0.05 moles the number of gram molecules is 0.05-gram molecules.

Hence, the number of gram molecules is 0.05.
