Answer:

1.) Answer: of atoms (molecules)÷ avogadro no. Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water.

2.)How many moles are in 8.30 X 1023 molecules of H2O? 1.38 moles H2O

3.)1 mol of water contains 6.022 × 1023 H2O molecules Therefore 0.500 mol contains 0.500 × (6.022 × 1023) = 3.01 × 1023 H2O molecules.

4.)6.02x1023 atoms

5.) 9.03x1023 atoms Hg 9.03x1024 atoms Hg 903 atoms of Hg

6.)6.022×1023

7.)1.51x1023 atoms Rb

8.)0.048 moles

9.)2.04

10.)How many moles are in 5.25 X 1025 atoms of Au? 87.2 moles Au
