Two cars leave a town at the same time and travel at constant speeds along straight roads that meet at an angle of 60° in the town. If one car travels twice as fast as the other and the distance between them increases at the rate of 63 mi/h, how fast is the slower car ...


1 atmosphere=101.325 kpa Use this to work out the pascal value and then use the ideal gas equation to find out the moles. Once you have done this use the n=m/M equation to find out what the relative molecular mass is :)

Math (urgent) hw due tommorow!
The speed of a stream is 3 km/h. A boat travels 25 km upstream in the same time it takes to travel 35 km downstream. What is the speed of the boat in still water?
