Answer:

Negatively Charged if the atom is neutral.

Explanation:

Electrons themselves have a negative charge.

When you add an electron to an atom that is neutral, the atom becomes negatively charged.

Take Sodium (Na) for example. It has 11 (positive) protons and 11 (negative) electrons - it's neutral.

What does conductivity have to do with solutions?

sergiy2304 [10]

Answer:

The relationship between conductivity and the number of ions in solution means that it can be used to measure solution concentration and give a value for Total Dissolved Solids. This means that measurements are of the total concentration of ions in solution not the concentration of any one ion.

The conversion factor 100mL/1 L would be used to change what

ValentinkaMS [17]

Answer:

Liters to milliliters.

Explanation:

Conversion factors are used to convert from one unit to another. The unit you are converting from goes in the denominator, and the unit you are converting to goes in the numerator. Since liters is in the denominator, you are converting from liters to another unit. Since milliliters is in the numerator, you are converting to that unit. Therefore, you would be converting from liters to milliliters.

1. Metformin (C4H11N5) is an oral diabetes medicine that helps control blood sugar levels. Each tablet contains 500.0 mg of metf

SSSSS [86.1K]

This problem is describing the molecular formula of Metformin as an oral diabetes medicine to control the blood sugar levels and is asking for the molar mass, moles in a single tablet and the total moles Jennifer consumes in a daily treatment. The results are 129.164 g/mol, 0.003871 mol and 0.02323 mol, respectively, according to the following work:

Firstly, we the molar mass of metformin, we multiply the subscript of each atom by its atomic mass and then we add them up as shown below:

$M.M=4*12.01+11*1.01+5*14.01=129.164g/mol$

Secondly, we convert the mg of each tablet to grams and then divide the previously obtained molar mass to calculate the moles in a single tablet:

$500.0mg*\frac{1g}{1000mg} *\frac{1mol}{129.164g} =0.003871mol$

Finally, we calculate the total number of moles she eats, assuming she gets three meals eaten in a single day and takes two per meal, which means there is a total of six tablets per day:

$6*500.0mg*\frac{1g}{1000mg} *\frac{1mol}{129.164g}=0.02323mol$
