Phenazopyridine is used to treat pain, burning, increased urination, and increased urge to urinate. These symptoms are usually caused by infection, injury, surgery, catheter, or other conditions that irritate the lower urinary tract.
<u>Answer:</u> The molar mass of the sample is 120.6 g/mol
<u>Explanation:</u>
To calculate the depression in freezing point, we use the equation:
Or,
where,
= depression in freezing point = 0.42°C
i = Vant hoff factor = 1 (For non-electrolytes)
= molal freezing point elevation constant = 5.065°C/m
= Given mass of solute (sample) = 0.500 g
= Molar mass of solute (sample) = ? g/mol
= Mass of solvent (benzene) = 50.0 g
Putting values in above equation, we get:
Hence, the molar mass of the sample is 120.6 g/mol

Answer:
88 grams CO2
Explanation:
Convert from grams to moles to mole ratio to grams again
32 g CH4 * 1 mol CH4/16 g CH4 * 1 mol CO2/1 mol CH4 * 44 grams CO2 = 88 grams CO2
Lemme know if u need more explanation!
There are 6 atoms of oxygen on the reactant side of the following equation: 2Fe2O3 + 3C → 4Fe + 3CO2. Details about atoms can be found below.
<h3>How to find number of atoms?</h3>
The number of atoms of an element in a balanced equation is the amount of that element involved in the reaction.
According to this question, Iron oxide reacts with carbon to produce iron and carbon dioxide as follows:
2Fe2O3 + 3C → 4Fe + 3CO2
In this reaction, 2 × 3 atoms = 6 atoms of oxygen are present on the reactant side of the equation.
