A student performed a similar experiment we have done, with Ag and O to produce silver oxide. Mass of crucible and lid: 29.307 g
Mass of crucible, lid, and silver: 30.958 g
Mass of crucible, lid, and silver oxide: 31.080 g
Use the above data to calculate the moles of the metal used in this experiment. your answer must include correct significant figures and unit.

0.0153 mol

Explanation:

Mass of crucible and lid: 29.307 g

Mass of crucible, lid, and silver: 30.958 g

Number of moles = Mass /Molar mass

Mass of Silver = Mass of crucible, lid, and silver  -  Mass of crucible and lid

Mass of siilver = 30.958 g - 29.307 g

Mass of silver = 1.651 g

Molar mass of silver = 107.868 g/mol

Number of moles = 1.651 g / 107.868 g/mol

Number of moles = 0.0153 mol
