A doctor's order is 0.500 g of ampicillin. The liquid suspension on hand contains 250 mg/5.0 mL. How many milliliters of the suspension are required?

The volume of the suspension required : 10 ml

Given

0.500 g of ampicillin

The liquid suspension concentration = 250 mg/5 mL

Required

The volume of the suspension required

Solution

The concentration of a substance can be expressed in various units such as molarity, ppm, g / L etc.

Each unit change, we must pay attention to the conversion factor

Conversion g to mg

0.5 g = 500 mg

The volume of the suspension needed :

=mass x concentration

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
