How many V atoms are there in a 26.3 gram sample of V?
To determine the number of V (Vanadium) atoms in a sample, we need to follow these steps:
1. Find the molar mass of Vanadium: The molar mass of an element represents the mass of one mole of that element. The molar mass of Vanadium (V) is 50.94 g/mol.
2. Calculate the number of moles: To find the number of moles in the sample, we divide the given mass by the molar mass.
Moles of V = Mass of V / Molar mass of V
Moles of V = 26.3 g / 50.94 g/mol
3. Use Avogadro's number: Avogadro's number (6.022 x 10^23) represents the number of particles (atoms, molecules) in one mole of a substance.
Number of V atoms = Moles of V x Avogadro's number
Number of V atoms = (26.3 g / 50.94 g/mol) x (6.022 x 10^23)
Now, let's calculate the number of V atoms:
Number of V atoms = (26.3 / 50.94) x (6.022 x 10^23)
To get the final answer, you need to perform the calculation using a calculator or computational tool.
