<span>Oceanic crust is denser than continental crust. This is partly why the continents are at a higher elevation than the ocean floor.</span>
Carbon=10.0
Hydrogen=6.7
Oxygen=53.5
Next, divide by their atomic masses. The atomic masses of the elements are;
Carbon=12, Hydrogen=1, Oxygen=16
So that will be
Carbon=40/12=3.3
Hydrogen=6.7/1=6.7
Oxygen=53.5/16=3.3
Next, divide by the smallest number. The smallest number is 3.3
Carbon=3.3/3.3=1
Hydrogen=6.7/3.3=2
Oxygen=3.3/3.3=1
So the empirical formula will be
C₁H₂O₁ which is the same as CH₂O
To get the molecular formula;
(CH₂O)n=molecular mass
Now we need to find n
(CH₂O)n=60
Multiply the atomic masses of each by the subscript and add them all
C₁=12 x 1=12
H₂=1 x 2=2
O₁=1 x 16=16
(12+2+16)n=60
(30)n=60
Divide both sides by 30
therefore; n=60/30
n=2
Next, multiply CH₂O by 2
C=1 x 2=2
H₂=2 x 2=4
O=1 x 2=2
So you have the empirical formula to be C₂H₄O₂
Hope that helped. Have a nice day
Answer:
Nobelium is made by the bombardment of curium (Cm) with carbon nuclei. Its most stable isotope, 259No, has a half-life of 58 minutes and decays to Fermium (255Fm) through alpha decay or to Mendelevium (259Md) through electron capture.
Explanation:
According to my calculations, C should be correct as 1.00 mole of any substance is 6.022 x 10^23 which is known as Avogadro's number.
C6H6 is benzene, an organic compound. I would imagine it would be immiscible, since most organic compounds don’t dissolve in water very well.
