What mass in g does 3.99 moles of Kr have?
3,99 moles of Kr have 334,35 g.
How many moles are contained in 1.23 grams of krypton?
To determine the number of moles in 1.23 grams of krypton, first find the molar mass of krypton (Kr), which is approximately 83.80 g/mol. Then, divide the given mass (1.23 g) by the molar mass of krypton to find the number of moles. In this case, 1.23 g / 83.80 g/mol ≈ 0.015 moles of krypton.
How is a number of moles of an element determined from a known mass?
The number of moles is mass in g/molar mass in g.
How many moles are in 103.56 g of Fe3(PO4)2?
To find the number of moles in 103.56 g of Fe₃(PO₄)₂, first calculate its molar mass. The molar mass of Fe₃(PO₄)₂ is approximately 357.43 g/mol. Using the formula: moles = mass (g) / molar mass (g/mol), we get: moles = 103.56 g / 357.43 g/mol ≈ 0.29 moles.
What is the amount in moles in 26.1 g Ta?
To find the amount in moles of tantalum (Ta) in 26.1 g, you can use the formula: moles = mass (g) / molar mass (g/mol). The molar mass of tantalum is approximately 180.95 g/mol. Thus, moles of Ta = 26.1 g / 180.95 g/mol ≈ 0.144 moles.

The number of moles is mass in g/molar mass in g.
What mass of He contains the same number of atoms as 5.0 g Kr?
To find the mass of He containing the same number of atoms as 5.0 g Kr, we need to use the fact that atoms are indivisible entities. First, determine the number of atoms in 5.0 g Kr using the molar mass of Kr. Then, calculate the mass of He containing the same number of atoms by dividing the atomic mass of He by Avogadro's number and scaling it up to match the number of Kr atoms.
What number of moles are present in 10.0 g aspartame?
To find the number of moles in 10.0 g of aspartame, we first need its molar mass. Aspartame has a molar mass of approximately 294.3 g/mol. Using the formula: moles = mass (g) / molar mass (g/mol), we calculate: moles = 10.0 g / 294.3 g/mol, which is approximately 0.034 moles of aspartame.
What is the amount in moles in 26.1 g Ta?
To find the amount in moles of tantalum (Ta) in 26.1 g, you can use the formula: moles = mass (g) / molar mass (g/mol). The molar mass of tantalum is approximately 180.95 g/mol. Thus, moles of Ta = 26.1 g / 180.95 g/mol ≈ 0.144 moles.
How many moles of AlCN3 are in 229 g of the compound?
To find the number of moles of AlCN3 in 229 g of the compound, you first need to determine the molar mass of AlCN3. The molar mass of AlCN3 is 144.99 g/mol.
