A solution is made up by dissolving 47.5 g of potassium iodide (KI) in 300cm³ of water. Calculate the concentration of Kl in mole/litre.

please I need the calculations​

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?

Large helium-filled balloons are used to lift scientific equipment to high altitudes. what is the pressure inside such a balloon if it starts out at sea level with a temperature of 10.0ºc and rises to an altitude where its volume is twenty times the original volume and its temperature is – 50.0ºc ?

What statement goes against the kinetic theory of gases
