Answer:
2.02 * 10⁸ L
Explanation:
Moles is denoted by given mass divided by the molecular mass ,
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molecular mass .
From the question ,
w = 700 mg ,
(since , 1 mg = 10 ⁻³ g)
hence , w = 0.700 g
m = molecular mass of HgI₂ = 454.4 g/mol .
Calculating moles by using the above formula ,
n = w / m = 0.700 g / 454.4 g/mol = 1.54 * 10⁻³ mol.
From the question ,
7.62 x 10⁻⁶ umol/L = 7.62 * 10⁻¹² mol / L
Since , 1 umol = 10 ⁻⁶ mol
The Volume in terms of liters is -
volume = 1 L * 1.54 * 10⁻³ mol / 7.62 * 10⁻¹² mol / L = 2.02 * 10⁸ L
