Answer:
0.12 mole.
Explanation:
From the question given above, the following data were obtained:
Molarity of NaCl solution = 0.1 M
Volume of NaCl solution = 1.2 L
Mole of NaCl =.?
Molarity of a solution is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is expressed as:
Molarity = mole /Volume
Thus, we can obtain the mole of NaCl in the solution by using the above formula as follow:
Molarity of NaCl solution = 0.1 M
Volume of NaCl solution = 1.2 L
Mole of NaCl =.?
Molarity = mole /Volume
0.1 = mole of NaCl /1.2
Cross multiply
Mole of NaCl = 0.1 × 1.2
Mole of NaCl = 0.12 mole
Therefore, 0.12 mole of NaCl is present in the solution.

Answer:
There are 1.253*10²⁴ particles in 2.080 moles
Explanation:
Avogadro's number is called the number of particles that make up a substance (usually atoms or molecules) that can be found in the amount of one mole. In other words, Avogadro's number is the number of molecules that one mole of any substance contains. Its value is 6.023 * 10²³ particles per mole.
So, you can apply a rule of three as follows: if 1 mole has 6.023*10²³ particles, then 2.080 moles, how many particles does it have?
amount of particles= 1.253*10²⁴ particles
<u><em>There are 1.253*10²⁴ particles in 2.080 moles</em></u>
I would say it is impossible to transfer the location of energy.
