Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2​
marissa [1.9K]

Answer:

A 0.015M

Explanation:

Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:

Molarity (M) = mole (n) / volume (L)

Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.

We can calculate the number of moles of KCl in the solution by using the formula:

Mole = mass ÷ molar mass

Where atomic mass of; K = 39, Cl = 35.5

Molar Mass of KCl = 39 + 35.5

= 74.5g/mol.

Mole = 0.83g/74.5g/mol.

mole = 0.01114

Approximately, n = 0.011mol

Hence, molarity = 0.011mol/0.75L

Molarity = 0.0146

Molarity = 0.015M

Justin has decided that he wants to involve his employees in all of the different steps of decision making: identifying problems
adoni [48]

Justin has decided that he wants to involve his employees in all of the different steps of decision-making: identifying problems, generating alternatives, selecting solutions, planning implementations, and evaluating results. If he does this, he can expect that employee performance and job satisfaction will increase.

<h3>What is job satisfaction?</h3>

A measure of a worker's contentment with their job, whether they like the job or specific features or facets of occupations, such as the nature of the job or supervision, is called job satisfaction, employee satisfaction, or work satisfaction. The cognitive (or evaluative), affective (or emotional), and behavioral components of job satisfaction can all be assessed. Researchers have also highlighted that different job satisfaction measures vary in how much they represent thoughts or feelings about the job.

Employee performance is characterized by how well they carry out their job responsibilities and complete their assigned tasks. It speaks to the usefulness, excellence, and efficacy of their output. Performance is a factor in how valuable we consider each person to be to the company.
