What else can I help you with?
What critical piece of information must be known in order to determine the molecular formula?
To determine the molecular formula of a compound, one must know its molar mass. This information, coupled with the molecular weight of its individual elements, allows for the calculation of the ratio of atoms present in the compound, and subsequently leading to the determination of its molecular formula.
Can you determine the molecular formula of a substance from its percent composition?
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
What is Meyer's oscillating disc method?
Meyer's oscillating disc method is a technique used to determine the molecular weight of a polymer by measuring the change in weight of a solution containing the polymer as it oscillates at a specific frequency. This method allows for accurate determination of molecular weight and can be used to study the size and structure of macromolecules.
What is the molecular weight of 18 crown ether?
264.122 g/molSee the Web Links to the left of this answer for more information.
What additional information do you need to determine the molecular formula?
To determine the molecular formula, you need the molecular weight of the compound, the empirical formula, and any information about the compound's structure or the number of atoms of each element present. Additionally, knowing the types of elements involved can also help in calculating the molecular formula accurately. If the empirical formula is known, the ratio of the empirical formula's mass to the molecular weight will help in finding the actual molecular formula.
What is the molecular weight of chymotrypsin?
It has a molecular weight of 21,600 Daltons
What is the molecular weight and molecular formula of potassium humate?
molecular structur C9H8K2O4molecular weight: 258.35
What is the structural difference between a fat that is solid at room temperature vs a fat that is a liquid at room temperature?
Usually, the one that is solid has a higher molecular weight
If you have molecular weight how can you find equivalent weight?
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
What is the molecular weight of vanillideneacetone?
The molecular weight of vanillideneacetone is 192.214g/mol.
