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 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?

The molar mass of sodium (Na) is approximately 23 g/mol. To find the mass of 0.0135 moles of Na, multiply the number of moles by the molar mass: 0.0135 moles * 23 g/mol ≈ 0.3105 grams of Na.


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.


How many grams of sodium are in a 1 mole sample of sodium?

The molar mass of an element corresponds to the atomic mass of the element (found on the periodic table). The atomic mass of Sodium-Na is 22.990 g, which is also the molar mass of Na. So for 1 mole of Na, there are 22.990 grams of Na. If we had 3 moles of Na, then we would simply multiply the molar mass by 3.


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.
