How many molecules are there in 8.00 grams of glucose, C6H12O6

Chemistry
1 answer:
beks73 [17]3 years ago
6 0

Answer:

molecules C6H12O6 = 2.674 E22 molecules.

Explanation:

from periodic table:

⇒ molecular mass C6H12O6 = ((6)(12.011)) + ((12)(1.008)) + ((6)(15.999))

⇒ Mw C6H12O6 = 180.156 g/mol

⇒ mol C6H12O6 = (8.00 g)(mol/180.156 g) = 0.0444 mol C6H12O6

∴ mol ≡ 6.022 E23 molecules

⇒ molecules C6H12O6 = (0.0444 mol)(6.022 E23 molecules/mol)

⇒ molecules C6H12O6 = 2.674 E22 molecules

A mole equals 6.02 x 10^23 . Answer these questions below.
siniylev [52]

Answer:

1. 1.25 mol ants x 6.02*10^23 ants/1 mol ants = 7.53*10^23 ants

2. 4.92*10^26 pencils x 1 mol pencils/6.02*10^23 pencils = 817 mol pencils

3. 0.26 mol molecules x 6.02*10^23 molecules/1 mol molecules = 1.6*10^23 molecules

4. 3.46*10^19 molecules x 1 mol molecules/6.02*10^23 molecules = 5.75*10^-5 mol molecules

5. 5.3*10^20 atoms x 1 mol atoms/6.02*10^23 atoms = 8.8 mol atoms

6. 0.11 mol atoms x 6.02*10^23 atoms/1 mol atoms = 6.6*10^22 atoms

I would suggest looking into "dimensional analysis" for help with this type of material. Dimensional analysis will stick with you all throughout chemistry, so picking it up will be extremely beneficial.

How many excited electron in the atom with an electron configuration of [kr]5s24d55p6 ?
IRISSAK [1]
The ground-state electronic configuration follows the order of orbitals as shown in the first picture. So, we can deduce that the electronic configuration given is in order. However, each orbital must have a maximum number of electrons to be filled before it can move on to the next orbital. Since the d orbital must hold 10 electrons, that means that it should have held 5 electrons more. The missing 5 electrons were excited to the next 5p orbital. <em>Thus, there are 5 excited electrons.</em>
