If I have the following number of molecules of sulfur dioxide, how many grams is that?
4.57 x 1025 molecules

Mass = 4871.6 g

Explanation:

Given data:

Number of molecules of sulfur dioxide = 4.57 × 10²⁵ molecules

Mass in gram = ?

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.

1 mole = 6.022 × 10²³ molecules

4.57 × 10²⁵ molecules × 1 mol / 6.022 × 10²³ molecules

0.76× 10² mol

76 mol

Mass of sulfur dioxide:

Mass = number of moles × molar mass

Mass = 76 mol × 64.1 g/mol

Mass = 4871.6 g

explanation:

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
