What is the name of the ionic compound AlBr3?
Aleksandr [31]

Answer: Correct name will be is aluminum bromide

Explanation:

In a molecular formula ,AlBr_3

Aluminium atoms present = 1  

Bromine atoms present = 3

Charge on aluminium is +3 and charge on bromine is -1.

While naming:

  • Name of the cation is written first. Simple name of the element is written
  • After name of cation name of an anions written with suffix 'ide' in the end.

So, the name of AlBr_3 will be aluminium bromide.

A solution of 62.4 g of a covalent compound in enough water to make 1.000 L of solution has an osmotic pressure of 0.305 atm at
Alborosie

Answer:

4.99 × 10³ g/mol

Explanation:

Step 1: Given  and required data

  • Mass of the covalent compound (m): 62.4 g
  • Volume of the solution (V): 1.000 L
  • Osmotic pressure (π): 0.305 atm
  • Temperature (T): 25°C = 298 K

Step 2: Calculate the molarity (M) of the solution

The osmotic pressure is a colligative pressure. For a covalent compound, it can be calculated using the following expression.

π = M × R × T

M = π / R × T

M = 0.305 atm / (0.0821 atm.L/mol.K) × 298 K

M = 0.0125 M

Step 3: Calculate the moles of solute (n)

We will use the definition of molarity.

M = n / V

n = M × V

n = 0.0125 mol/L × 1.000 L = 0.0125 mol

Step 4: Calculate the molar mass of the compound

0.0125 moles of the compound weigh 62.4 g. The molar mass is:

62.4 g/0.0125 mol = 4.99 × 10³ g/mol
