How many moles in the compound magnesium sulfate and water?
To determine the number of moles in a compound like magnesium sulfate and water, you need to know the mass of each individual component in the compound. Then you can use the molar mass of each substance to convert the masses to moles using the formula: moles = mass / molar mass. Keep in mind that in a compound like magnesium sulfate and water, you need to consider the molar ratios of each component in the compound.
What do the prefixes in a covalent compound name tell when writing the chemical formula?
The prefixes in a covalent compound name indicate the number of each element present in the compound. The prefixes are used to determine the subscripts in the chemical formula, specifying how many atoms of each element are bonded together.
How can you tell how many atoms of each element there are?
You can determine the number of atoms of each element in a compound by using the chemical formula of the compound. The subscripts in the formula indicate the number of atoms of each element. For example, in H2O (water), there are 2 hydrogen atoms and 1 oxygen atom.
What does oxidation number for an element tell you?
The oxidation number of an element tells you the charge that the element would have if electrons were transferred completely during the formation of a compound. It can help to determine the type of chemical reactions that an element is likely to undergo.
What do the subscript numbers represent in a chemical formula?
They tell you how often an atom - or a group of atoms - are repeated.
What does an element's molar mass tell you about the element?
An element's molar mass represents the mass of one mole of that element in grams. It tells you the average atomic mass of the element, which is the sum of the protons and neutrons in the nucleus of its atoms. Molar mass helps in determining the amount of substance in moles when given the mass of the sample.
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.
How many moles in the compound magnesium sulfate and water?
To determine the number of moles in a compound like magnesium sulfate and water, you need to know the mass of each individual component in the compound. Then you can use the molar mass of each substance to convert the masses to moles using the formula: moles = mass / molar mass. Keep in mind that in a compound like magnesium sulfate and water, you need to consider the molar ratios of each component in the compound.
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.
Is Uranium a compound tell its elements?
Uranium is not a compound. It is an element.
If the solid after heating has a molar mass of 208 grams per mole and a formula of XY what is the formula of the hydrate?
The molar mass of the hydrated compound is 208 g/mol. To find the formula of the hydrate, we need to determine the molar mass of the anhydrous compound (XY) and subtract it from the total molar mass. With that information, we can calculate the molar mass of water in the hydrate and determine the ratio between XY and water molecules, giving us the formula of the hydrate.
How do you tell the number of moles in a compound if given the number of grams?
Multiply the mass of the compound by the conversion factor based on the percent composition of the element in the compound
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
What does percent composition tell you about a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
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.
