Answer:
A. is the correct answer because Boron has 3 electrons too,
All elements in Group 13 have three electrons in their outermost energy level. The two most popular elements in this group are Boron and Aluminum.
First, find the molar mass of C6H12O6 (180.156 g/mol)
Then, using avagadro's number (6.02*10^23), find the amount of molecules in the sample.
(2.3*10^-3g)/180.156 g/mol = 0.0000128 mol
(0.0000128 mol)(6.02*10^23)= 7.6856*10^18 molecules
Answer:
Explanation:
I’m pretty sure that stories differ because they are not proven and can be easily manipulated. Scientific explanations are proven and are probably fact.
