Answer 1

Answer:

answer =2

Explanation:

mole =wt.of substance / molar mass

molar mass of h2so4=98

mole=196/98

mole=2

Answer 2

98 grams/moles.

Molar mass of the Sulfuric acid = 2 + 32 + 64

= 98 grams/moles.

Given, Mass of the Sulfuric acid = 196 g.

.: No. of molecules of the Sulfuric acid =

No. of moles x Avogadro's number.

.. No. of molecules of the Sulphuric acid

2 x 6.022 x 10²³

= 12.044 x 10²³ molecules.

Now, 1 molecule of the sulfuric acid contains 1 sulfur atoms.

.:12.044 x 10²³molecules of the sulfuric acid contains 12.044 × 10²³ sulfur atoms.
