Asingle atom of platinum has a mass of 3.25x10^-22g. what is the mass of 6.0x10^23 platinum atoms?

                    194.36 g

Data Given:

                 Number of Atoms  =  6.0 × 10²³

                 A.Mass of Platinum  =  195.08 g.mol⁻¹

Step 1: Calculate Moles of Platinum,

                   Moles  =  Number of Atoms ÷ 6.022 × 10²³ Atoms.mol⁻¹

Putting value,

                   Moles  =   6.0 × 10²³ Atoms ÷ 6.022 × 10²³ Atoms.mol⁻¹

                   Moles  =  0.9963 mol

Step 2: Calculate Mass of Platinum:

                   Moles  =  Mass ÷ M.Mass

Solving for Mass,

                   Mass  =  Moles × M.Mass

Putting values,

                   Mass  =  0.9963 mol × 195.08 g.mol⁻¹

                   Mass  =  194.36 g

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
