How many grams are in 11.9 moles of chromirum
faust18 [17]

Answer:

Explanation:

Method 1 proportion

1 mole of chromium is 52 grams

11.9 moles = x grams

1/11.9 = 52/x                    Cross multiply

x = 11.9 * 52

x = 618.8                         grams

Now I have used an approximate mass for Chromium. The answer you get here is expected to reflect the weigth given on your periodic table Use that to get your answer. You should give a number very close to mine. Round to 3 places as in 619.

Method Two  Formula

mols = given mass / molecular mass

11.9 = given mass /  51.9961          Multiply both sides by  51.9961

11.9 *51.9961  = given mass            

given mass = 618.75

given mass = 619

Compare and contrast the ease at which molecules are able to move relative to each other in the three states of matter
ANTONII [103]
The arrangement of molecules within the 3 phases of matter are shown in the picture. 

For the solid, the molecules are packed closely together. They don't have much space to move, so they just practically vibrate. For the liquid, the molecules are relatively farther from each other. The liquid molecules can flow freely but not as much as the gases. In the gases, the molecules are very far from each other. They are very sensitive to slight changes of pressure, volume and temperature.
