What is the molar mass of al2(so4)3? 150.03 g/mol 278.03 g/mol 342.17 g/mol 450.09 g/mol

The molar mass of is 342.17 g/mol

Explanation:

Molar mass of a compound is defined as the total mass which is calculated by adding up the individual mass of atoms each multiplied by the number of atoms.

Aluminium sulfate is a compound made from aluminium, oxygen and sulfur atoms.

Molar mass of Aluminium = 26.981 g/mol

Molar mass of Sulfur = 32.065 g/mol

Molar mass of Oxygen = 15.999 g/mol

Molar mass of

Hence, the molar mass of is 342.17 g/mol

b. atoms in metallic solids are not arranged in a regular pattern

explanation:

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
