olchik [2.2K]3 years ago
5 0

Answer:

2 moles of C-12 have 24g mass

Explanation:

Given data:

Number of moles of C-12= 2 mol

Mass of C-12 = ?

Solution:

Formula:

Number of moles = mass / molar mass

Molar mass of C-12 = 12 g/mol

Now we will put the values in formula.

2 mol  = mass / 12 g/mol

Mass = 2 mol ×  12 g/mol

Mass = 24 g

Thus 2 moles of C-12 have 24 g mass.

In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions)
jeyben [28]

Answer:

Li2S> Na2S> K2S> CsS

Explanation:

The lattice energy of ionic species depends on the relative sizes of ions in the ionic compounds. As the size of ions increases, the lattice energy decreases and vice versa.

When the size of the anions are the same, the lattice energy now depends on the relative sizes of the cations. Therefore, since all the compounds are sulphides and the order of magnitude of ionic sizes is: Li^+ < Na^+ < K^+ < Cs^+.

Therefore, the order of decrease in lattice energy is; Li2S> Na2S> K2S> CsS

How many molecules are there in 8.00 grams of glucose, C6H12O6
beks73 [17]

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
