The maximum number of balloons that can be inflated has to be calculated Concept Introduction: An ideal gas has is a hypothetical gas that is formed by a few molecules so that, its density is low, and the intermolecular forces are null. The model of gas facilitates mathematical calculations to study gases. The ideal gas law can be expressed in the following way, P x V= n x R x T Where P is the gas pressure (atm), V is the gas volume (L), T is the gas absolute temperature (K), n is the moles number of the gas and R is the ideal gas constant ( R=0 .082 atm L K mol ). In the STP conditions, the temperature is 273 K and the pressure is 1 atm.

Question

2. Platinum and other group 10 metals often act as solid phase hydrogenation catalysts for unsaturated hydrocarbons such as propylene, CH3CHCH2. In order for the reaction to be catalyzed the propylene molecules must first adsorb onto the surface. In order to completely cover the surface of a piece of platinum that has an area of 1.50 cm² with propylene, a total of 3.45 x 10¹7 molecules are needed. Determine the mass of the propylene molecules that have been absorbed onto the platinum surface.

Interpretation:

The maximum number of balloons that can be inflated has to be calculated

Concept Introduction:

An ideal gas has is a hypothetical gas that is formed by a few molecules so that, its density is low, and the intermolecular forces are null. The model of gas facilitates mathematical calculations to study gases.

The ideal gas law can be expressed in the following way,
P x V= n x R x T
Where P is the gas pressure (atm), V is the gas volume (L), T is the gas absolute temperature (K), n is the moles number of the gas and R is the ideal gas constant ( R=0.082 atm LK mol ).

In the STP conditions, the temperature is 273 K and the pressure is 1 atm.

Chem 141, Dr. Haefner 2. (a) Many main group oxides form acidic solutions when added to water. For example solid tetraphosphorous decaoxide reacts with water to produce phosphoric acid. Write a balanced chemical equation for this reaction. (b) Calcium phosphate reacts with silicon dioxide and carbon graphite at elevated temperatures to produce white phosphorous (P4) as a gas along with calcium silicate (Silcate ion is SiO3²-) and carbon monoxide. Write a balanced chemical equation for this reaction.

Problem Set 4a Chem 1411. A latex balloon is filled with a total of carbon dioxide gas so that its volume reaches 1.352 L. The balloon whose weight was originally 0.753 g, now weighs 2.538 g. How many molecules of carbon dioxide have been added to the balloon?
