What is the atomic mass of the element in grams per mole (g/mol)?

The atomic mass of an element is the average mass of one atom of that element, measured in atomic mass units (amu). This value is also equivalent to the mass of one mole of atoms of that element, expressed in grams per mole (g/mol).


How is the mass in grams of an element converted to amount in moles?

1 mol of any element is the atomic weight expressed in grams.


Which is always equal to the molar mass of any element?

The atomic mass of an element is equal to its molar mass in grams/mol.


What is the mass of 1.6 mol of the element?

To find the mass of 1.6 moles of an element, you need to know the molar mass of that element (found on the periodic table). Multiply the molar mass by the number of moles (1.6) to get the mass in grams. Thus, by multiplying the molar mass by 1.6 mol, you can find the mass of 1.6 moles of the element.


What is the molar mass of all ther elements?

The molar mass of an element is the atomic mass of that element expressed in grams/mol. The molar mass of each element varies depending on its atomic number and isotopic composition. Common elements like hydrogen, carbon, oxygen, and nitrogen have molar masses of approximately 1 g/mol, 12 g/mol, 16 g/mol, and 14 g/mol, respectively.


If the atomic mass of an element is x what is the mass in grams of 6.021023 atoms of the element?

To find the mass of 6.02 x 10^23 atoms of an element, you would multiply the atomic mass of the element (x) by Avogadro's number (6.02 x 10^23 molecules/mol) to get the mass in grams. The result would be x grams.


What is the mass of 2.25 mol of the element iron fe?

The answer is 125,65 g.


What is the mass of 0.41 mol of the element potassium?

The molar mass of potassium (K) is approximately 39.10 g/mol. To find the mass of 0.41 mol of potassium, you would multiply the molar mass by the number of moles: 39.10 g/mol * 0.41 mol = 16.049 g. So, the mass of 0.41 mol of potassium is approximately 16.049 grams.


What is the mass in grams of 0.0135 mole of the element Na?

molar mass Na = 22.99g/mol (atomic weight in grams) 0.0135mol Na x (22.99g/mol) = 0.310g Na


What is the mass in grams of 5.01 mol of xenon?

The mass in grams of 5,01 mol of xenon is 657,778 g.


What is the mass in grams of 0.330 mol of calcium?

To find the mass in grams of 0.330 mol of calcium, you need to multiply the number of moles by the molar mass of calcium. The molar mass of calcium is approximately 40.08 grams/mol. So, 0.330 mol * 40.08 g/mol = 13.23 grams of calcium.


What is the mass in grams of 2 mol of 12C?

The molar mass of carbon is approximately 12 grams/mol. Therefore, the mass of 2 moles of 12C is 24 grams (12 g/mol x 2 mol).
