    14.8 * 10²³ molecules

    Explanation:

    Given dа ta:

    Mass of sulfuric acid = 240 g

    Number of molecules = ?

    Solution:

    The given problem will solve by using Avogadro number.

    It is the number of atoms, ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

    The number 6.022 * 10²³ is called Avogadro number.

    For example,

    18 g of water = 1 mole = 6.022 * 10²³ molecules of water

    1.008 g of hydrogen = 1 mole = 6.022 * 10²³ atoms of hydrogen

    Number of moles of sulfuric acid

    Number of moles = mass / molar mass

    Number of moles = 240 g / 98 g/mol

    Number of moles = 2.45 mol

    Number of molecules:

    1 mole = 6.022 * 10²³ molecules

    2.45 * 6.022 * 10²³ molecules

    14.8 * 10²³ molecules
