The number of molecules of methane should be calculated Concept Introduction: Raoult's Law: It states that the partial pressure of gas in a mixture is equal to the product of the total pressure of a gas and its mole fraction. The mathematical expression is: P A = X A ⋅ P t o t a l Where, P A = Partial pressure of gas A, X A = mole fraction of gas A and P t o t a l = vapor pressure of mixture. The partial pressure of gas A is obtained by the multiplication of mole fraction of gas A and total pressure of mixture. According to the relation, the partial pressure of gas A is directly proportional to its mole fraction implies with increase in the mole fraction, the partial pressure of a gas is also increases whereas with decrease in the mole fraction, the partial pressure of a gas is also decreases.

Interpretation Introduction

Interpretation:

The number of molecules of methane should be calculated

Concept Introduction:

Raoult's Law:

It states that the partial pressure of gas in a mixture is equal to the product of the total pressure of a gas and its mole fraction.

The mathematical expression is:

PA=XA⋅Ptotal

Where, PA = Partial pressure of gas A, XA = mole fraction of gas A and Ptotal = vapor pressure of mixture.

The partial pressure of gas A is obtained by the multiplication of mole fraction of gas A and total pressure of mixture.

According to the relation, the partial pressure of gas A is directly proportional to its mole fraction implies with increase in the mole fraction, the partial pressure of a gas is also increases whereas with decrease in the mole fraction, the partial pressure of a gas is also decreases.

Shown below is the mechanism presented for the formation of biasplatin in reference 1 from the Background and Experiment document. The amounts used of each reactant are shown. Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.) (Hints: The first step is correct, the second step is not; and the amount of the anhydride is in large excess to serve a purpose.)
