The mass of 2.75 mol K₂S is 303.24 grams.
- Applying the mole concept:
Number of moles(n) = given mass(m) / molar mass(M)
n = m / M
- Now applying the formula for the number of moles-
i.e. number of moles of K₂S = mass of K₂S / Molas mass of K₂S
As per question, Molar mass of K₂S, M = 110.27 g/mol
and, number of moles of K₂S, n = 2.75 moles
2.75 = m / 110.27
m = 2.75 x 110.27
= 303.24
m = 303.24 grams.
Hence, the mass of 2.75 mol K₂S is 303.24 grams.

Explanation:
A single-replacement reaction replaces one element for another in a compound.
A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds.
A precipitation reaction is a double-replacement reaction in which one product is a solid precipitate.
Solubility rules are used to predict whether some double-replacement reactions will occur.
Answer:
I know you have been waiting awhile for this question to be answered :)
Stoichiometry is used in industry quite often to determine the amount of materials required to produce the desired amount of products in a given useful equation. Each one of these products requires stoichiometry. There would be no products from these industries without chemical stoichiometry.
Explanation:
Hopefully this helps :D
Sorry you had to wait so long :(
Its hybridization would be sp because Be only has 2 covalent bonds with Cl
The answer to this question would be: <span> 10 °K
Kelvin and Celcius scales are different by 273</span> degrees but their ratio is the same. One degree in Kelvin is equal to one degree in Celcius. That mean, 10 °C change in Celcius would be same as <span> 10 °K changes in Kelvin too. </span>
