The mole fraction of acetone (C₃H₆O) is 0.333
<h3>Data obtained from the question </h3>
- Mole of C₃H₆O = 0.1 mole
- Mole of CHCl₃ = 0.2 mole
- Mole fraction of C₃H₆O =?
<h3>How to determine the mole fraction </h3>
Mole fraction of a substance can be obtained by using the following formula:
Mole fraction = mole / total mole
With the above formula, we can obtain the mole fraction of C₃H₆O as follow:
- Mole of C₃H₆O = 0.1 mole
- Mole of CHCl₃ = 0.2 mole
- Total mole = 0.1 + 0.2 = 0.3 mole
- Mole fraction of C₃H₆O =?
Mole fraction = mole / total mole
Mole fraction of C₃H₆O = 0.1 / 0.3
Mole fraction of C₃H₆O = 0.333

Yes, because nothing has changed. The same ingredients are used and if one reaction happened in a a bag then why wouldn’t it happen in a container?
H2O is the chemical formula of water. It means that each molecule of water is made up of two hydrogen atoms, indicated by the letter H, and a single oxygen atom, represented by the O. Water is a chemical substance with no smell, taste, or color.
Answer:
The suitable equation for this reaction is
2CO + O₂ -----> 2CO₂
Here, we are given that we have 2 grams of O₂
From the equation, we can see that 2 * Moles of O₂ = Moles of CO₂
Moles of O₂:
2/32 = 1/16 moles
Therefore, the number of moles of CO₂ is twice the moles of O₂
Moles of CO₂ = 2 * 1/16
Moles of CO₂ formed = 1/8 moles
Mass of CO₂ formed = Molar mass of CO₂ * Moles of CO₂
Mass of CO₂ formed = 44 * 1/8
Mass of CO₂ formed = 5.5 grams
Hence, option B is correct

A standard solution is a solution (in this case sodium hydroxide) whose concentration (molarity) is known very precisely. <span>The molarity of the sodium hydroxide solution cannot be determined accurately because s</span>olid sodium hydroxide is highly hygroscopic (absorbs water from the air) and cannot be accurately weighed. Sodium hydroxide form sodium carbonate because it absorbs carbon
dioxide from the air.
