How many total moles of ions are released when the following sample dissolves completely in water? enter your answer in scientific notation. 4.55 × 10^15 formula units of sr(hco3)2 = mol

The number of moles of strontium bicarbonate is

Explanation:

Formula units are defined as lowest whole number ratio of ions in an ionic compound. It is calculate by multiplying the number of moles by Avogadro's number which is

We are given:

Number of formula units of

As,  number of formula units are contained in 1 mole of a substance.

So, number of formula units will be contained in = of strontium bicarbonate.

Hence, the number of moles of strontium bicarbonate is

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
