<span>Glucose is the human body's key source of energy as it provides energy to all the cells in our body. Glucose also is critical in the production of proteins, lipid metabolism and is a precursor for vitamin C production.</span><span><span>Glucose is the sole source of fuel to create energy for all brain and red blood cells.</span> The availability of glucose influences many psychological processes. When glucose levels are low, psychological processes requiring mental effort l(self-control, critical thinking and decision-making) become impaired.

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
