Answer:
1.566x10²⁴ atoms of Cl
Explanation:
In Carbon tetrachloride, CCl₄, you have 4 moles of Cl per mole of CCl₄. To solve this question we must find the moles of CCl₄ in order to find the moles of Cl. Using Avogadro's number we can solve the chlorine atoms:
<em>Moles CCl₄: 153.82g/mol</em>
100g * (1mol / 153.82g) = 0.65 moles CCl₄
<em>Moles Cl:</em>
0.65 moles CCl₄ * (4 moles Cl / 1mol CCl₄) = 2.6 moles Cl
<em>Atoms Cl:</em>
2.6 moles Cl * (6.022x10²³ atoms / mol) =
<h3>1.566x10²⁴ atoms of Cl</h3>
A periodic table is tabular arrangement of the chemical elements, ordered by their atomic number,electronic configuration and recurring chemical properties. carbon is in group 14 and period two. The atomic mass of carbon from periodic table is 12.01 g/mole
Answer:Reliability
Explanation:
Reliability of a test refers to how consistently a test measures a characteristic under the same conditions.
Reliability can be defined as the degree of consistency of which a chemical test gives a similar result. measure. A test is said to be highly reliable when it gives the same repeated result under the same conditions of measure.
But when a test gives different results under the same condition of measure it has a low reliability.
Hence, If a test yields consistent results every time it is used, it has a high degree of reliability.
It is the mass of one mole of the substance.
