Question

What is the molar mass of pure tin?

a) 1.00 g/mol
b) 47.88 g/mol
c) 118.71 g/mol
d) 237.42 g/mol

Answer 1

The molar mass of pure tin is C, 118.71 g/mol.

Answer 2

The molar mass of pure tin is
`118.71 g/mol`, which corresponds to option (c) from the multiple-choice options provided.

Step-by-step explanation:

The molar mass of pure tin (Sn) is
`118.71 g/mol` , which corresponds to option (c) in the provided choices. The molar mass of a substance is defined as the mass of one mole of its particles, which can be atoms, molecules, or formula units, depending on the substance being considered. The molar mass of each element is found on the periodic table as the atomic weight of that element and is expressed in grams per mole (g/mol).

For example to find the molar mass of pure tin, one would simply look at the atomic weight of tin on the periodic table. Since
`1.00 mole` of any element has a mass numerically equal to its atomic mass in grams, the molar mass of tin is equal to its atomic weight. Therefore, given tin's atomic weight of approximately
`118.71 g/mol` we are able to determine the molar mass of pure tin.
