Determine the mass of cisplatin produced from 2.5 g K2PtCl4 reacting with excess ammonia

Answer 1

first step: what is the balanced reaction equation?
Next: How many moles of K2PtCl4 do you have in 1.5g?
Next: How many moles of product do you get for each mole of K2PtCl4? Do the math.
Finally: convert that back to grams.

Answer 2

The equation is K2PtCl4 + 2NH3 → 2KCl + Pt(NH3)2Cl2
