The Earth holds livings things and even the layer has more complex layers in it (Also it's not white) And of course there are no oceans
Answer:
60.8%
Explanation:
We'll begin obtaining the molar mass of cobalt(II) fluoride, CoF2. This can be done as shown below:
Molar mass of CoF2 = 59 + (19x2) = 97g/mol.
The percentage composition of cobalt in cobalt(II) fluoride, CoF2 is given by:
Mass of Co/Molar Mass of CoF2 x 100
=> 59/97 x 100 = 60.8%
Therefore, the percentage composition of cobalt in cobalt(II) fluoride, CoF2 is 60.8%
The answer is B I believe
the answer is 0.0693769. 6.02x10^21 x6.94/ 6.022x10^23 is the formua you would use.
