Answer:
Explanation:
I want to believe that your question is how to find an 8M carbon chloride solution using the given mass of the compound.
The problem clearly identifies with concentration of a substance. Molarity is one of the ways of expressing concentration. It is the amount of solute of a substance per volume of solution.
Molarity =
To find the right mix that will give us 8M carbon chloride solution, let's explore how to figure out the appropriate volume.
Clearly given is the mass of the compound, convert to number of moles.
Number of moles =
Molar mass of carbon chloride(CCl₄) = 12 + 4(35.5) = 154g/mol
Number of moles = = 0.57moles
To find the volume;
8 =
volume = 0.071L or 71mL
Answer:
Some examples of homoatomic molecules are hydrogen gas, and oxygen gas and some examples of heteroatomic molecules are water, methane
Explanation:
Atoms of elements is the answer. Hope this helps
Answer:
29.41% of Calcium and 47.04% of Oxygen
Explanation:
The percent composition of an atom in a molecule is defined as 100 times the ratio between the mass of the atom and the mass of the molecule.
The mass of the molecule of the problem (Ore) is 46.28g. That means the percent composition of Calcium is:
13.61g / 46.28g * 100 = 29.41% of Calcium
And percent composition of Oxygen is:
21.77g / 46.28g * 100 = 47.04% of Oxygen
