How many atoms are in the element copper and in the element carbon and in the element aluminum and how many atoms are in baking soda and how many atoms are in a sugar cube?
There are no "atoms in an element," but rather atoms OF an element. If you are trying to find the number of atoms in a sample of a pure element you divide its weight by its molar mass and then multiply by 6.022 x 10^23 to get the answer in atoms. The answer options are 2,3, or 4.
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.
How many atoms are in 70.620 g of rhenium?
To determine the number of atoms in a given mass of an element, you need to know the molar mass of that element. The molar mass of rhenium (Re) is 186.207 g/mol. To find the number of atoms in 70.620 g of rhenium, divide the given mass by the molar mass, and then multiply by Avogadro's number (6.022 x 10^23). This gives approximately 1.590 x 10^23 atoms of rhenium.
How atoms and elements differ from one another?
An element is a composition of many atoms. Thus you can hold NaCl (salt) in your hand. You can't hold the atoms it makes up.

How many atoms in c8h18?
the molar mass of Octane is 114.
How would we know how many moles are in a certain element?
number of moles = mass of the element/molar mass of the element
What is a molar mass and how many atoms are in 1 mole of anything?
molar mass is just the moleular mass of an atom or molecule.
How many atoms does 100 grams of gold have?
Gold has a molar mass of 196.96655 grams per mole. 100 grams then is equal to .508 moles which makes 3.059 E23 atoms of gold.
How many atoms are there in an element?
This depends on the mass of this element.
What is right numerically atoms for gold to be element?
Gold is the element gold no matter how many atoms of it you have.
What is the molar mass of KOH?
molar mass is the mass of one mole of a substance. A mole is an amount, refers to Avogadros number which is 6.022 x 1023. a mole of atoms is that many atoms. therefore the molar mass of potassium hydroxide KOH is the mass of that many molecules of KOH. On the periodic table the mass number for each element is molar, so all you need to do is add together the molar mass of each element in the compound. Molar mass of potassium (K) is 39 Molar mass of oxygen (O) is 16 Molar mass of hydrogen (H) is 1 There is one of each of these elements in a molecule of potassium hydroxide therefore the molar mass = 39 + 16 + 1 = 56
