6.7 grams of aluminum sulfate to moles

0.01958mol

Step-by-step explanation:

you want to go from grams to mols so when set up it looks like this

6.7 x

(you want what your multiplying to cancel out with the denominator(g cancel out g so your left with mols))

to get the mass of aluminum sulfate you must first find the chemical formula which is

Al2(SO4)3

get the amount of every element

so there is:

2 Al

3 S

12 O

(multiply the three to everything inside the parenthesis)

next find the total mass of everything

Al=26.982g x 2

S=32.06g x 3

O=16g x 12

add everything together and you get 342.144g so you plug that number into the first equation

6.7 x → →0.01958mol

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
