Q. Iron has a mass of 7.87 g per cubic centimeter of volume, and the mass of an iron atom is 9.27 × 10-26 kg. If you simplify and treat each atom as a cube, (a) what is the average volume (in cubic meters) required for each iron atom and (b) what is the distance (in meters) between the centers of adjacent atoms?
Q. A 318 mL container holds 0.146 g of Ne and an unknown amount of Ar at 35°C and a total pressure of 624 mmHg. Calculate the moles of Ar present.

A uniform plank of length 5.70 m and weight 215 N rests horizontally on two supports, with 1.1 m of the plank hanging over the right support. To what distance x can a person who weighs 452 N walk on the overhanging part of the plank before it just be..
A car is traveling at a constant speed of 38.8m/s on a highway. At the instant this car passes an entrance ramp, a second car enters the highway from the ramp. The second car starts from rest and has constant acceleration. What acceleration must it..
Compute the average linear velocity of the discus
A plot of pressure as a function of volume is known as a pV diagram. pV diagrams are often used in analyzing thermodynamic processes. Consider an ideal gas that starts in state O, as indicated in the diagram. Your task is to explain how the gas proce..
