Question

Cisplatin,an anticancer drug, has the molecular formula pt(NH3)2CL2 .What is the mass (in grams) of one molecule? (atomic weight of pt is 195)

Answer 1

Answer:

This is the mass of 1 mole of a molecule. According to mole concept: 1 mole of a compound ontains number of molecule. This means that, mass of molecules is 300 grams.

Since molar mass of cisplatin =300

Mass of 1molecule = molar mass/ 6.022 × 10^23

= 300 / 6.022 × 10^23

= 3×1.66 ×10^-24

= 4.98 ×10^-22
