<span>chemical combination of two or more elements in definite proportions. For example, two hydrogen molecules + one oxygen molecule= one water molecule. A solution is a physical combination of two or more chemicals mixed evenly (salt that is dissolved in water). Solutions are also known as homogenous mixtures. A mechanical mixture is a physical combination of two or more chemicals that are not evenly mixed (hot fudge on ice cream). </span>
Answer:
9.9 moles of Ag₂S contain 9.9 moles of sulfur.
Explanation:
Given data:
Number of moles of Ag₂S = 9.9 mol
Number of moles of Sulfur = ?
Solution:
One mole of Ag₂S having 1 mole of sulfur.
In 9.9 moles:
9.9 moles × 1 = 9.9 moles
So 9.9 moles of Ag₂S contain 9.9 moles of sulfur.
