What substance has a molecular weight of 765.82?
The substance with a molecular weight of 765.82 is the antibiotic called Azithromycin.
How can one determine the theoretical mass of a substance?
To determine the theoretical mass of a substance, one must calculate the molecular weight of the substance by adding up the atomic weights of all the atoms in its chemical formula. This can be done using the periodic table to find the atomic weights of each element present in the substance.
How would you test an unknown substance for to determine what organic molecules it contained?
You could start by performing tests such as chromatography to separate the different components in the substance and identify their properties. Mass spectrometry could help determine the molecular weight of the compounds present. Lastly, infrared spectroscopy can provide information on the functional groups present in the organic molecules.
Can one substance have same empirical and molecular formula?
Yes, it is possible for a substance to have the same empirical and molecular formula. This can occur when the substance is composed of only one type of element, such as oxygen gas (O2), where both the empirical and molecular formula are O2.
What is the significance of the molecular mass (symbol) in determining the properties of a substance?
The molecular mass (symbol) of a substance is significant in determining its properties because it affects how the substance interacts with other molecules. Substances with higher molecular masses tend to have different physical and chemical properties compared to substances with lower molecular masses. This is because the molecular mass influences factors such as boiling point, melting point, and solubility, which are important in understanding the behavior of a substance.
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 a gram of a molecular substance?
A gram of a molecular substance is the quantity that will have a mass of 1 gram.
Which substance shows a substance that is not molecular?
A formula unit.
What is the that shows the no. of atoms and it's kind in a substance?
The molecular formula provides these information .
What substance has a molecular weight of 765.82?

To determine the theoretical mass of a substance, one must calculate the molecular weight of the substance by adding up the atomic weights of all the atoms in its chemical formula. This can be done using the periodic table to find the atomic weights of each element present in the substance.
What is the freezing point of a substance with a molecular weight of n2?
The freezing point of a substance with a molecular weight of N2 is -210.01 degrees Celsius.
What does the state of a substance depend on?
Typically pressure and temperature determine whether a substance is gas, liquid or solid. Some substances however are not easily forced into some of the states, and that is determined by by individual molecular qualities.
How would you test an unknown substance for to determine what organic molecules it contained?
You could start by performing tests such as chromatography to separate the different components in the substance and identify their properties. Mass spectrometry could help determine the molecular weight of the compounds present. Lastly, infrared spectroscopy can provide information on the functional groups present in the organic molecules.
What is identity of a substance?
The identity of a substance (chemical compound) is defined by his chemical formula and molecular structure.
What are the characteristics of a molecular substance?
o hai
What is a molecule a group of?
A Molecular Substance or Compound.
