I would personally convert the 12 mg to g so I could see what I was working with. So 12 mg to grams is 0.012 g...

so 1 tablet is 0.012g. the patient needs 0.024 g. 

so 0.024g/0.012g = 2 tablets or 0.012g X 2 is 0.024 g

hope this helps :)

Answer : The number of tablets given should be, 0.5

Explanation :

We are given :

Mass of sulfa drug for a patient = 0.024 g

Total mass of tablets = 12 mg = 12\times 10^{-3}g=0.012g

(Conversion factor: 1 g = 1000 mg)

To calculate the number of tablets, we divide the total mass of tablets to the mass of sulfa drug for a patient.

n=\frac{\text{Total mass of tablets}}{\text{Mass of sulfa drug for a patient}}

Putting values in above equation, we get:

n=\frac{0.012g}{0.024g}\\\\n=0.5

Hence, the number of tablets given should be, 0.5

Murrr4er [49]
<span>NaCl is poster-compound for ionic bonding. The bonds in NaCl have about 70% ionic character, making the bond highly polar. its overstatement to state that there is actual ion in NaCl with +1 and -1 charge but actual charge of Na and Cl is +1 and -1 ion, since Nacl exist as a network of highly charged particle and not discrete molecule, NaCl particle does not exhibit intermolecular forces. Water molecule on other hand exhibit London dispersion force, keesom force, and hydrogen bonding. The polar water molecule are attracted to the polarized Na and Cl atoms. This is what allow NaCl(s) to dissolve and ionize in water. Therefore type of attraction in NaCl is ion-dipole attraction.</span>
