<h3>What is the concertation of a solution?</h3>

The concentration of a solution is the amount of solute dissolved or present in a given volume of solution.

Concentration of solutions can be expressed as either:

  • molar concentration
  • mass concentration
  • percentage concentration

The concentration of the sugar solutions are given as percent concentration.

The 5% sugar solution contains 5% sugar and 95% water

The 10% sugar solution contains 10% sugar and 90% water.

Therefore, the 5% sugar solution contains more water.

inysia [295]

Oxygen gas produced : 0.7 g

<h3>Further explanation</h3>

Given

10.0 grams HgO

9.3 grams Hg

Required

Oxygen gas produced

Solution

Reaction⇒Decomposition

2HgO(s)⇒2Hg(l)+O₂(g)

Conservation of mass applies to a closed system, where the masses before and after the reaction are the same

mass of reactants = mass of products

mass  HgO = mass Hg + mass O₂

10 g = 9.3 g + mass O₂

mass O₂ = 0.7 g
