How many atoms are there in 6.26 g Si?
.250 mole 7.02 ------ 28.09 = .250
How many moles are there in 237 g of niobium?
To find the number of moles in 237 g of niobium, divide the given mass by the molar mass of niobium, which is approximately 92.91 g/mol. Number of moles = 237 g / 92.91 g/mol ≈ 2.55 moles.
How many moles dose 11 grams of silicon contain?
11 g x 1 mol Si/28.0855 g Si= 0.39 mol Si 205g He x 1mol He/4.002602 g He=51.2 mol He
How many atoms of sulfur (S) are in 5 g of sulfur?
5 g of sulfur contain 0,94.10e23 atoms.
How many atoms of C are in a 56 g?
The number of atoms is 28,099.10e23.
How many grams are there in one atom of neptunium?
The atomic mass of neptunium is approximately 237 grams per mole. Since 1 mole of any element contains Avogadro's number of atoms (approximately 6.022 x 10^23 atoms), one atom of neptunium would weigh approximately 237 grams divided by Avogadro's number, which is a very tiny fraction of a gram.
How many atoms are there in 6.26 g Si?
.250 mole 7.02 ------ 28.09 = .250
How many atoms are in 49.1740 g of zirconium?
49.1740 g (6.02 x 1023 atoms) / (91.22 g) = 3.25 x 1023 atoms
How many moles are there in 237 g of niobium?
To find the number of moles in 237 g of niobium, divide the given mass by the molar mass of niobium, which is approximately 92.91 g/mol. Number of moles = 237 g / 92.91 g/mol ≈ 2.55 moles.
How many representative particles are in 1.45 g of a molecular compound with a mass of 237 g?
1.45 g of a molecular compound with a molar mass of 237 represents 1.45/237 or 6.118 X 10-3 mole. Assuming that "representative particles" in the question means "molecules", this is (6.118 X 10-3){Avogadro's Number} or 3.68 X 1021 molecules.
How many atoms are in 38.260 g of chlorine?
6,687.1023 chlorine atoms
How many atoms are in g Pb?
The number of atoms of lead is 6,68.10e23.
How many moles dose 11 grams of silicon contain?
11 g x 1 mol Si/28.0855 g Si= 0.39 mol Si 205g He x 1mol He/4.002602 g He=51.2 mol He
How many atoms of sulfur (S) are in 5 g of sulfur?
5 g of sulfur contain 0,94.10e23 atoms.
How many moles of silicon are in 245 g of silicon?
To find the number of moles in 245 g of silicon, divide the given mass by the molar mass of silicon. The molar mass of silicon is 28.09 g/mol. Therefore, 245 g ÷ 28.09 g/mol ≈ 8.71 moles of silicon.
How many representative particles are in 1.45 g of a molecular compound with a molar mass of 237 g?
There are 6.02 x 10^23 representative particles (molecules) in 1 mole of a substance. To find the number of representative particles in 1.45 g of a compound with a molar mass of 237 g, you first need to determine the number of moles in 1.45 g of the compound using the formula: moles = mass / molar mass. Then, multiply the number of moles by Avogadro's number to find the number of representative particles.
How many total atoms are in 0.220 g of P2O5?
There are 1.15 x 10^21 atoms in 0.220 g of P2O5.
