Answer:
false?
Explanation:
The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds
First, find the number of moles of glucose in 30.5 g.
You need the molar mass.
Molar mass of C6H12O6 = 6 * 12.01 g/mol + 12 * 1.01 g/mol + 6*16g/mol = 180.2 g/mol
number of moles = mass in grams / molar mass = 30.5 g / 180.2 g/mol = 0.169 mol
Second, use molecular formula
1 mol of C6H12O6 contains 6 moles of O.
Then, 0.169 moles of C6H12O6 contains 6 *0.169 = 1.014 moles of O.
Third, multiply by Avogagro's number:
1.014 moles * 6.022 * 10^23 atoms / mole = 6.106 * 10^ 23 atoms.
Answer: 6.106 * 10 ^23 atoms of oxygen.
