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.
