Answer: Option (C) is the correct answer.

Explanation:

An amphipathic molecules is defined as the molecule that contains both polar and non-polar parts.

For example, phospholipids are amphipathic molecules as they contain non-polar fatty acids known as tails and polar phosphate known as heads.

In amphipathic molecules, the polar water molecules tend to pull towards each other. As a result, non-polar parts tend to move away into the air.

Therefore, we can conclude that amphipathic molecules line up at a water surface because polar groups attract one another.

An iron atom has a mass of ×9.2710−23g and a cooking pot has a mass of 0.500kg
morpeh [17]

The number of iron atoms in a cooking pot that has a mass of 0.500 kg can be solve by dividing it by the mass of the iron atom.

Number of iron atoms = ( 0.5 kg) (1000g / 1kg) ( 1 iron atom / 9.27 x 10^-23 g)

<span>Number of iron atoms = 5.39 x 10 ^24 iron atoms</span>

Which of the following statements concerning a metal crystallized in a face-centered cubic cell is/are CORRECT? 1. One metal ato
AleksAgata [21]

Answer:

Only 3 is correct.

Explanation:

The crystal of a metal or an ionic compound is called a cell, and there are 7 types of unit cells: cubic, tetragonal, orthorhombic, monoclinic, hexagonal, rhombohedral, and triclinic.

In a face-centered cubic cell (FCC) all angles are 90º and all lengths are equal. Each cubic cell has 8 atoms in each corner of the cube, and that atom is shared with 8 neighboring cells. So for a metal crystal, the atom is located at each of the eight lattice points, where it is shared equally between eight unit cells.

How many grams of CaF2 are present in 1.25 L of a 0.15 M solution of CaF2? How do I find the grams I am confused on that part?
dybincka [34]

Answer:

Mass = 14.64 g

Explanation:

Given data:

Volume of solution = 1.25 L

Molarity of Solution = 0.15 M

Mass of CaF₂ = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

We will calculate the number of moles of CaF₂ and then determine the mass by using number of moles.

0.15 M =  number of moles of solute / 1.25 L

number of moles of solute = 0.15 M ×  1.25 L

number of moles of solute = 0.1875 mol/L × L

number of moles of solute = 0.1875 mol

Mass in gram:

Mass = number of moles × molar mass

Mass = 0.1875 mol ×78.07 g/mol

Mass = 14.64 g
