Answer:
2.67 mL
Explanation:
The following data were obtained from the question:
Mass of tetracycline = 2 mg
Density of tetracycline = 0.75 mg/mL
Volume of tetracycline =?
We can obtain the volume of the tetracycline that should be given to the patient by applying the following equation:
Density = mass /volume
0.75 = 2 / volume
Cross multiply
0.75 × Volume = 2
Divide both side by 0.75
Volume = 2/0.75
Volume = 2.67 mL
Therefore, the volume of the tetracycline that should be given to the patient is 2.67 mL
The correct question is as follows:
How do you convert from grams to moles of a substance
1. Divide by the molar mass
2. Subtract the molar mass
3. Add the molar mass
4. Multiple by the molar mass
Answer: In order to convert from grams to moles of a substance divide by the molar mass.
Explanation:
The number of moles of a substance is the mass of substance in grams divided by its molar mass.
The formula to calculate moles is as follows.
This means that grams are converted to moles when grams is divided by molar mass.
Thus, we can conclude that in order to convert from grams to moles of a substance divide by the molar mass.
