Answer:
A. 3+
Explanation:
In the complex, the global charge is -1.
There are 2 molecules of H₂O but water is a neutral ligand that doesn't contribute any charge to the complex
In contrast, the C₂O₄ ligand has a charge of -2. As there are 2 C₂O₄, the charge is -4.
The -4 + The charge of Cr is equal to global charge of the complex ion = -1.
Thus, Cr has a charge of +3 and right answer is:
<h3>A. 3+</h3>
Answer:
7.307 x 10^-23
Explanation:
mass of one molecule = mr/ avogadros number
= 44/6.022 x 10^23
= 7.307x 10^-23
M H2O = 18 g/mol
In 18 g of water we have 6,02 × 10^23 molecules.
18 g ----- 6,02 × 10^23
36 g ----- x
x = 36 g × 6,02 × 10^23 / 18 g = 12,04 × 10^23 = 1,204 × 10^24
Answer is 1,204 × 10^24
