Answer:
Mass of Cr = 0.25376 gram
Moles of Fe = 0.0011875
Mass of Te = 0.05472 gram
Moles of Ti = 7.9764
Explanation:
Given:
Elements Moles Mass
Cr 0.00488
Fe 66.5 mg = 0.0665
Ti 48
Hg 1.60 kg = 1600
Computation:
Mass = Atomic mass x moles
Moles = Mass / Atomic mass
Atomic mass
Cr = 52 u
Fe = 56 u
Te = 127.6 u
Hg = 200.59 u
Mass of Cr = 0.00488 x 52
Mass of Cr = 0.25376 gram
Moles of Fe = 0.0665 / 56
Moles of Fe = 0.0011875
Mass of Te = 1.14 x 10⁻³ x 48
Mass of Te = 0.05472 gram
Moles of Ti = 1600 / 200.59
Moles of Ti = 7.9764
