Molecules are chemical structures made of atoms; molecular weight is the mass of a molecule, while molar mass is the mass of one mole of a substance.

• Molecules consist of two or more atoms bonded together, e.g., H2O (water) or CO2 (carbon dioxide).

• Molecular weight is the sum of the atomic weights of all atoms in a molecule, e.g., H2O has a molecular weight of about 18 g/mol.

• Molar mass is the mass of one mole of a s...read more

Chemical formulas represent the composition of substances using symbols and numbers for elements and their quantities.

• Chemical formulas use element symbols from the periodic table (e.g., H for hydrogen, O for oxygen).

• Subscripts indicate the number of atoms of each element (e.g., H2O has 2 H atoms and 1 O atom).

• For compounds with multiple elements, the order is usually based on electronegativity or standard convent...read more

Quality control ensures products meet required standards, enhancing safety, efficacy, and customer satisfaction in production processes.

• Monitors raw materials for consistency and compliance with specifications.

• Conducts in-process testing to identify defects early, such as checking pH levels in chemical production.

• Implements final product testing to ensure safety and efficacy, like testing pharmaceuticals for poten...read more

To dilute a 12% NaOH solution to 5%, calculations involve using the formula C1V1 = C2V2 and determining the amount of water needed.

• Use the formula C1V1 = C2V2, where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.

• Calculate the volume of the initial 12% NaOH solution needed using the formula V1 = (C2 * V2) / C1.

• Subtract the initial volume from th...read more

Flash distillation is a single-stage process where a liquid mixture is vaporized quickly, while fractional distillation is a multi-stage process where the mixture is separated into fractions based on boiling points.

• Flash distillation is a rapid vaporization process used for separating components with large differences in boiling points.

• Fractional distillation is a slower process that involves multiple distillation...read more
