Osmosis deals only with D. Water. Diffusion and Osmosis are relatively the same thing besides the fact that water is largely incorporated with the osmosis.
Mass= number of mole *Molar mass
mass =2.92 mol*87.62 g/mol≈256 g
The units of density are g/ml. If you find the grams of 1 mol of ethanol (with the molecular weight), you can then divide by the density to get the ml of ethanol.
g*(ml/g)=ml
We have the compound: KSCN, Potassium thiocyanate, in an aqueous solution.
The dissociated reaction of the salt:
KSCN (aq) => K+ + SCN-
It has 2 ions. One of them is the potassium ion, K+ (cation) and the other one is the thiocyanate ion, SCN- (anion).
Answer:
K+, the potassium ion
SCN-, the thiocyanate ion
humidity can be measured by the simplest hygrometer, called a sling psychrometer. It is composed of two thermometers placed together with a handle set to a chain. One of the thermometers is just like any other thermometer. Erstwhile the other one has a cloth wick wrapped over its bulb and is called a wet-bulb thermometer.
Have a great day!
