Question 2 of 3
3 millimoles of Acetylcholine Chloride weigh 545.1 milligrams. What is the RMM of Acetylcholine Chloride - to one decimal place?
Convert milligrams to grams: 545.1 mg = 0.001 x 545.1 g = 0.5451 g
Convert millimoles to moles: 3 mmoles = 0.001 x 3 mmoles = 0.003 moles
RMM = Mass of Component
Number of Moles
RMM of Acetylcholine Chloride = 0.5451
0.003
