If you’re wondering how many moles and atoms of zinc are in a sample weighing 34.9 g, we have your answer. To calculate this, you need to know the atomic mass of zinc. According to the Periodic Table of Elements, the atomic mass of zinc is 65.39 g/mol. To calculate the number of moles and atoms in the sample, we’ll use this formula: mass/atomic mass = moles. Let’s plug 34.9 into the equation:
34.9g/65.39 g/mol = 0.533 mol
This means that there are 0.533 moles of zinc in the sample. To calculate the number of atoms, we’ll use Avogadro‘s number, which is 6.02 x 1023 atoms/mol. We’ll plug 0.533 into the equation:
0.533 mol x (6.02 x 1023) atoms/mol = 3.2 x 1023 atoms of zinc.
Therefore, there are 0.533 moles and 3.2 x 1023 atoms of zinc in a sample weighing 34.9 g.
