Answer:
Explanation:
Hello,
In this case, since the solution is formed by sodium chloride and water, we understand that for one mole of solution, we have 0.132 moles of sodium chloride and 0.868 moles of water, therefore, by using their molar masses we can compute their masses in the solution:
Thereby, we can compute the weight/weight percent as follows:
So we use the previously computed masses:
Best regards.

Some of the properties are:
1. Gamma, γ-rays are not deflected by electric and magnetic fields. It shows that they do not have any charge.
2. Gamma, γ-rays are electromagnetic waves like X-rays. The wavelength of γ-ray photon is smaller than that of X-rays.
3. The rest mass of a Gamma, γ-ray photon is zero. (Photon has mass zero but it has momentum, why?)
4. Gamma, γ-rays travel with the speed of light.
5. Gamma, γ-rays have very large penetrating power. They can pass through several centimeter of iron and lead.
6. Gamma, γ-rays can produce fluorescene in a substance like willimite.

Answer: <span>The coordination number of the central metal ion in [Co(C</span>₂<span>O</span>₄<span>)2(OH)</span>₂<span>]</span>⁻³ <span> is
6.
Explanation: Coordination number is defined as the number of neutral atoms or ions surrounding the central metal atom.
In given case there are four ligands surrounding the Co central atom.
1) Oxalate Ion: Oxalate ion has two negative charges (shown below). So each oxalate makes two coordinate covalent bonds with central metal atom and four coordinate covalent bond by two Oxalate Ions.
2) Hydroxyl Ion: Hydroxyl ion has one negative charge. Hence it makes one coordinate covalent bond with Co atom.</span>
