Use the periodic table to determine the molar mass of each of the following elements. use the correct number of significant figures. potassium (k): g/mol osmium (os): g/mol manganese (mn): g/mol

Molar mass of Potassium(K) - 39.0983 g/mol  - six significant figures

Molar mass of Osmium(Os) - 190.23  g/mol  - five significant figures

Molar mass of Manganese(Mn) - 54.938044 g/mol  - eight significant figures

Explanation:

Molar mass:

The molar mass of a substance is the mass in grams of one mole of the substance.

Potassium atomic number is 19 and it is a 1A group element.

Molar mass of Potassium(K) - 39.0983 g/mol  - six significant figures

Osmium atomic number is 76 and it is VIIIB group element.

Molar mass of Osmium(Os) - 190.23  g/mol  - five significant figures

Manganese atomic number is 25 and it is VIIB group element.

Molar mass of Manganese(Mn) - 54.938044 g/mol  - eight significant figures.

The molar mass of potassium is 39.10 g/mol, osmium is 190.23 g/mol and that of manganese is 54.94 g/mol

Explanation:

Molar mass is defined as the mass of 1 mole of an element. It is expressed in g/mol.

For the given elements:

Potassium (K) is the 19th element of the periodic table present in Group 1 and Period 4. The molar mass of potassium is 39.10 g/mol

Osmium (Os) is the 76th element of the periodic table present in Group 8 and Period 6. The molar mass of potassium is 190.23 g/mol

Manganese (Mn) is the 25th element of the periodic table present in Group 7 and Period 4. The molar mass of potassium is 54.94 g/mol

Hence, the molar mass of potassium is 39.10 g/mol, osmium is 190.23 g/mol and that of manganese is 54.94 g/mol

the answer is alpha particles hope i you

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this
