Question

A bar of solid platinum metal has a mass of 0.3110 kg. Convert this mass to moles of platinum.

Answer 1

Answer #1

atomic mass of Platinum = 195 g/mol

given mass of platinum = 0.3110 Kg = 311 g

moles = mass/molar mass

moles = 311/195

= 1.59487

= 1.595 moles

moles of Platinum = 1.595 moles
