What volume of pediatric digoxin injection 0.1 mg/ml is required for a 75 mcg dose

0.75mL

Explanation:

we have the density that is 0.1mg/mL and the mass (75mcg)

The unit in which the mass is expressed is microgram, we must pass it to milligrams to have all the data in the same units

To know how many mg are 75mcg we apply a rule of three

The density formula is given by the following equation

now we clear the volume and replace the data

The necessary volume is 0.75 mL of pediatric digoxin injection

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.
