The field of study which is shown in the picture is known as archaeology and is denoted as option D.

<h3>What is Archaeology?</h3>

This is defined as the scientific study of the material remains of past human life and activities through gathering of fossils.

This is usually done by a professional referred to as an archaeologist who uses special techniques and methods in the execution of the processes involved.

In the diagram attached in the picture shown below, we can view rocks present which helps to preserve fossils.This is therefore the reason why archaeology was chosen as the most appropriate choice.

Calculate the molality, molarity, and mole fraction of FeCl3 in a 29.5 mass % aqueous solution (d = 1.283 g/mL).

faltersainse [42]

Answer:

molality FeCl3= 2.579 molal

molarity FeCl3 = 2.333 M

mol fraction FeCl3 = 0.0444

Explanation:

Step 1: Data given

Mass % = 29.5 %

Density = 1.283 g/mL

Molar mass FeCl3 = 162.2 g/mol

Step 2: Calculate mass solution

Suppose we have 1L = 1000 mL solution

Mass solution = 1.283 g/mL * 1000 mL = 1283 grams

Step 3: Calculate mass FeCl3

Mass FeCl3 = 0.295 * 1283 grams

Mass FeCl3 = 378.485 grams

Step 4: Calculate mass of water

Mass water = 1283 - 378.485 = 904.515 grams

Step 5: Calculate moles FeCl3

Moles FeCl3 = mass FeCl3 / molar mass FeCl3

Moles FeCl3 = 378.485 grams / 162.2 g/mol

Moles FeCl3 = 2.333 moles

Step 6: Calculate moles H2O

Moles H2O = 904.515 grams / 18.02 g/mol

Moles H2O = 50.195 moles

Step 7: Mol fraction FeCl3

Mol fraction FeCl3 = 2.333 / (50.195+2.333)

Mol fraction FeCl3 = 0.0444

Step 8: Calculate molality

Molality = moles FeCl3 / mass H2O

Molality = 2.333 moles / 0.904515 kg

Molality = 2.579 molal

Step 9: Calculate molarity

Molarity = moles / volume

Molarity FeCl3 = 2.333 moles / 1 L

Molarity FeCl3 = 2.333 M

Chemical symbols stand for?

myrzilka [38]

Answer Explanation:

If it is like H, or O or N or Na or Cl, those are the elements. Those are on the Periodic table. pH is the acidity and basicity of a substance, how acidic or basic(caustic) it is. mol is Moles. kPa is kilopascals. STP is standard temperature and pressure, at 0*C(Celsius), or 273.15 K(Kelvin), and 101,325 pascals, or 101.325 kilopascals.

Avagadro's Number is 6.022x10^23, the number of atoms in a mole. The Ideal Gas Law is P(Pressure in kPa) times V(Volume in L, liters) equals n(number of moles of gas) times R(the universal gas constant, or 8.3145 (L kPa/K mol) or 8.3145 liters kilopascals per Kelvin mole. that is just a few of them.
