2.87mL of 2.5 M K2SO4 are required to obtain 1.25 grams of the compound.

<h3>HOW TO CALCULATE VOLUME?</h3>

The volume of a substance can be calculated by dividing the number of moles of the substance by its molarity. That is;

volume = no. of moles ÷ molarity

According to this question, 2.5M K2SO4 are required to obtain 1.25 grams of the compound. The volume can be calculated as follows:

Molar mass of K2SO4 = 174.26 g/mol

moles of K2SO4 = 1.25g ÷ 174.26g/mol

moles of K2SO4 = 0.00717moles

Volume = 0.00717moles ÷ 2.5

Volume = 0.00287 L = 2.87mL.

Therefore, 2.87mL of 2.5 M K2SO4 are required to obtain 1.25 grams of the compound.

The ion [Co(NH3)6]2+
Romashka-Z-Leto [24]

Explanation:

The answer would be  B.

As paramagnetic with 3 unpaired electrons. Since there are 6 ligands around the Co+2 ion it isoctahedral and these ligands are neutral. This makes the overall charge on the complex +2 and therefore comes from the configuration for Co+2 which is [Ar] 3d7. Since it is in high spin you must fill all the orbitals with at least one electron and then pair up any that remain. If you do this, 3 unpaired electrons remain. Para magnetism occurs in substances with unpaired electrons.
