How many atoms are in 12 grams of NaOH

Chemistry

3 0

There are 5.4 × 10^23 atoms in 12 g NaOH .

<em>Step 1</em>. Convert <em>grams of NaOH to moles of NaOH </em>

Moles of NaOH = 12 g NaOH × (1 mol NaOH /40.00 g NaOH)

= 0.300 mol NaOH

<em>Step 2</em>. Convert <em>moles of NaOH to formula units (FU) of NaOH </em>

FU of NaOH = 0.300 mol NaOH × (6.022 × 10^23 Fu NaOH/1 mol NaOH)

= 1.81 × 10^23 FU NaOH

<em>Step 3</em>. Convert <em>FU of NaOH to atoms </em>

1.81 × 10^23 FU NaOH × (3 atoms/1 FU NaOH) = 5.4 × 10^23 atoms

Which statement below matches the correct response with the proper reasoning when comparing the volatility of CH2Cl2 with CH2Br2
Nutka1998 [239]

Answer:

b. CH₂Cl₂ is more volatile than CH₂Br₂ because of the large dispersion forces in CH₂Br₂

Explanation:

CH₂Cl₂ is more volatile than CH₂Br₂ (b.p of CH₂Cl₂ = 39,6 °C; b.p of CH₂Br₂ = 96,95°C). Thus, c. and d. are FALSE

Dipole-dipole interactions in CH₂Cl₂ are greater than the dipole-dipole interactions in CH₂Br₂ because Cl is more electronegative that Br (Cl = 3,16; Br = 2,96). But this mean CH₂Cl₂ is less volatile than CH₂Br₂ but it is false.

There are large dispersion forces in CH₂Br₂ because Br has more electrons and protons than Cl. Large disperson forces mean CH₂Br₂ is less volatile than CH₂Cl₂ and it is true.

I hope it helps!
