Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

Question

100%

Calculate the molar mass of each compound given below. HINT: We cannot get the molar mass of a compound directly from the periodic table as we did for atomic molar masses. To calculate the molar mass of a compound we add up the atomic molar masses of all atoms in the chemical formula.

Can you help me, please?

REMINDER: In order for your answers to exactly match the solutions provided for review problems,
round molar masses to two digits to the right of the decimal point when possible.
a) H₂S
b) iron(II) nitrate
