Answer:

350.64g

Explanation:

So first you must know that M is mol/L

Next solve the problem using dimensional analysis

2L NaCl (3 mol/L) = 6 mol NaCl

After you got the number of moles you should look at your periodic table to find the molar mass

I see that it's 58.44g/mol

Use dimensional analysis again!

6 mol (58.44g/mol) = 350.64g

Mass of 2.88x10^-4 mol of ascorbic acid

Lady bird [3.3K]

Molar mass C₆H₈O₆ = 176.12 g/mol

1 mole ------------------ 176.12 g
2.88x10⁻⁴ mole ------- ?

mass = 2.88x10⁻⁴ * 176.12 / 1

mass ≈ 0.05072 g

hope this helps!

Which of the following are isoelectronic?

OleMash [197]

Answer:

The correct answer is option C.

Explanation:

Isoelectronic species are those atoms or ions which same number of electrons.But they differ in physical and chemical properties.

Atomic number of nitrogen atom is 7.

$[N]=1s^22s^22p^3$

$[N]^{3-}=1s^22s^22p^6$

Number electron in nitride ions = $N^{3-}=10$

Atomic number of oxygen atom is 8.

$[O]=1s^22s^22p^4$

$[O]^{2-}=1s^22s^22p^6$

Number electron in oxide ions = $O^{2-}=10$

$[Ne]=1s^22s^22p^6$

Number of electrons neon = $Ne=10$

Hence, $N^{3-} , O^{2-} \& Ne$ are isoelectronic.
