What is the molar mass of sodium hypochlorite?
To find a molar mass, add the molar weight (frequently called the atomic mass) of each element of the formula. The formula for sodium hypochlorite is NaOCl. Use a periodic table.Na = 22.9898 g/mol x 1 = 22.9898 g/molO = 15.99994 g/mol x 1 = 15.99994 g/molCl = 35.453 g/mol x 1 = 35.453 g/molSum = 74.44274 g/molSo the molar mass of NaOCl is 74.442 g/mol (don't forget significant figures). You can also look up the molar mass of compounds in many reference books (for example, the CRC Handbook of Chemistry and Physics). You may be able to find a copy in your local or school library. If you have access to a computer you can search for the compound on WolframAlpha. If we do a search for sodium hypochlorite, we can see that the molar mass is 74.442 g/mol, verifying our work.
How do you find the molecular and empirical formulas?
There is no easy answer to this question. First, it depends what information you have to start with. Do you have the name? Do you know what elements are found in the substance?If you are given the name of the molecule, you can often find the molecular structure of that compound by simply using the Google search engine online and searching for the name. It is often give you the answer! There are certain compounds that you should be familiar with also. Also, there is a set of official rules that determine the name of a specific compound, so that if you have the formula, you can name it correctly, and if you have the name, you can determine the formula. Unfortunately, many chemicals also have common names that do not follow these rules, and you just have to memorize those, or look them up with Google.See the Related Questions and Web Links to the left for some information about how compounds are named and how to go from a formula to a name and vice versa.
What does the period number tell you?
It tells you the number of cations in the outer energy level of the element's atomic mass
A piece of iron weighing 85.65 g was burned in air The mass of the iron oxide produced was 118.37 g use the molar mass of iron to convert the mass of iron used to moles?
If 85.65g of iron forms 118.37g of the oxide, the mass of oxygen combined with this mass of iron is 32.72g. Calculate the number of moles of iron and oxygen which have combined (after all, the formula of a compound shows the ratio of the number of moles of each element combined). Do this by dividing the mass reacted by the Relative Atomic Mass of the element concerned. i.e. For Iron it is 85.65/55.8 and for Oxygen 32.72/16. This gives a mole ratio of Fe:O as 1.53:2.04 or 3:4 Therefore the formula is Fe3O4
Element A is in the same group as element B and the same period as element C Which two of the three elements are likely to have similar properties?
Element A and element B are the most likely to have similar properties because they belong in the same family, because if you know an element's family you can tell the number of valance electrons and the elements they react with. In periods, the properties are not alike, they slowly change in a pattern.
What does the mass per element tell you about a molecule?
These informations add knowledge about the chemical composition of a molecule and the molar mass.
What does the molar mass of an element or compound tell you?
How many grams of the substance are in a mole of the substance. The molar mass of Carbon, for example, is 12 g/mol. This means that every 6.02*10^23 atoms mass 12 grams.
What does atomic mass number elements symbol elements name and atomic mass tell you about the element?
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.
How do you find molar mass?
you need to find the relative atomic mass. without that, you can't find that information unless given to you. basically, molar mass is a mole. a huge unit, but if you have that one "mole" of hydrogen atoms, you will have a equivalent of 1 gram The molar mass is the sum of the atomic weights of elements contained in the molecule, expressed in g/mole.
What does an elements atomic mass tell about the atoms that make up that element?
It tells you the mass of how many protons and how many neutrons plus the tiny mass of the electrons. The electrons are about .0016 amu so they still have mass
What does the atomic mass tell you about the atom?
The Atomic Mass of an element tells you the average mass of an atom in the element.
What does the mass of an element tell you about a molecule?
it tells you how much of the molecule the element is
What does an element's atomic mass tell about the atoms that make up that element?
Atomic Mass is the no. of protons+no. of nuetron
Which of these is an element in the emancipation proclamation?
List the elements and I will tell you.
How can you tell if elements are isotopes when looking at several nuclear symbols of the same element?
Isotopes of an element have the same number of protons but different numbers of neutrons. When looking at several nuclear symbols of the same element, if the number of protons (atomic number) remains the same but the mass number changes, then the elements are isotopes of one another. The mass number is the sum of protons and neutrons in the nucleus.
What does the period number tell about an element?
its tell you the atomics mass that occurs
What does an element's atomic mass tell us about the atoms that make up that element?
atomic mass is the no. of protons+no. of nuetron
