How many grams are NaCl are required to prepare 200 mL of a 3.10 M solution?
rodikova [14]

The mass (in grams) of NaCl required to prepare the solution is 36.27 g

<h3>What is molarity?</h3>

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

<h3>How to determine the mole of NaCl</h3>
  • Volume = 200 mL = 200 / 1000 = 0.2 L
  • Molarity = 3.1 M
  • Mole of NaCl =?

The mole of NaCl in the solution can be obtained as follow:

Molarity = mole / Volume

Cross multiply

Mole = Molarity x Volume

Mole of NaCl = 3.1 × 0.2

Mole of NaCl = 0.62 mole

<h3>How to determine the mass of NaCl </h3>

We can obtain the mass of NaCl needed to prepare the solution as follow:

  • Molar mass of NaCl = 58.5 g/mol
  • Mole of NaCl = 0.62 mole
  • Mass of NaCl = ?

Mole = mass / molar mass

Cross multiply

Mass = mole × molar mass

Mass of NaCl = 0.62 × 58.5

Mass of NaCl = 36.27 g

Explain how the fossil record indicates a long history of<br> changing life forms.
LuckyWell [14K]

The fossil record essentially keeps track of the abundance and appearance of various fossils during different time periods. As time goes on, the fossils change. Using the fossil record, we can compare and contrast the fossils to develop theories about changing life forms and their connection to time.

Hope this helped :)
