"Under constant conditions of P(pressure) and T(temperature) (and R [gas constant]), write an equation showing d(density) written as a function of M(molecular mass)." I don't understand this, really! Please help! Thanks in advance!

2.01 g of sodium sulfate How would I figure out the number of moles of sulfure atoms in that sample?

I have a 7 mL solution with 3 mL of H2O added to the solution. How would I figure out the molarity of the solution?

I need help understanding and using the Cosmic Calander (ans in figuring out the dates certain events such as when our solar system was created). Can someone plz help me with this? Thnx in advance.

A certain car is capable of accelerating at a uniform rate of 0.85 m/s2. What is the magnitude of the car’s displacement as it accelerates uniformly from a speed of 83 km/h to one of 94 km/h? I don't get this question. How do you calculate displacement wi...

Need some help with Astronomy. I need to figure out the acceleration of gravity on the surface of certain planets. For example, I need to find the acceleration of gravity on Mars when the mass is .11 times the mass of Earth and the radius is .53 times the...

“Rotor” is a ride found in many amusement parks that consists of a hollow cylindrical room (roughly 8 ft in radius) that rotates around a central vertical axis. Riders enter the room and stand against the canvas-covered wall. The room begins to rotate...

This is pretty much what I'm looking for! Thanks!

To find the slope of a line: use this equation: (y2-y1)divided by (x2-x1 EX. your two points are (4,2) and (5,5). The equation would go like this: (5-2)/(5-4)=3/1=3. Therefore, the slope of the line is 3. About the y=mx+b, you plug in the slope in place o...

whoops, made a typo. It's sulfur, not sulfure.

awesome! thanks for the help!
