SF₆
Molar mass: 146.06 g/mol
mole = 25 : 146.06 = 0.171
molecules:
=0.171 x 6.02 x 10²³
=1.03 x 10²³
When finding empirical formulas decimals are fine so you wouldn't have to multiply all of them to turn into whole numbers. What you would do is divide each of those numbers by the smallest of those numbers and take the nearest whole number so if you had:
1.81 mol .6 mol and .3.61 mol you would divide each of those numbers by .6
and you would have 3, 1, and 6
for your problem you would divide them all by 1 and Carbon would be 2 (if your teacher normally has you round down at .5's then it would be 1) hydrogen would be 3 and oxygen would be 1.
C2H3O
Answer:
Yes you are right!!!!
Can i have brainliest please and i would be happy to help you again bye luv <3
Answer:
126.99g
Explanation:
NiO has a molar mass of 74.7 g/mol. This means that one mole of nickel (II) oxide has a mass of 74.7 grams. We can use stoichiometry/dimensional analysis to figure out how many grams are in 1.7 moles.
