Answer and Explanation:
The molar mass of KBr is 119.00 g/mole. To determine the molar mass of KBr we need the molar masses of potassium (K) and bromine (Br).

Beside this, what is the molar mass of KBr?

119.002 g/mol

Beside above, what is the formula to find molar mass? The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol). The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.

What is Molality formula?

The formula for molality is m = moles of solute / kilograms of solvent. In problem solving involving molality, we sometimes need to use additional formulas to get to the final answer. One formula we need to be aware of is the formula for density, which is d = m / v, where d is density, m is mass and v is volume.

How do I calculate moles?

Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.

Do coefficients affect molar mass?

No. The coefficient (number in front) is the number of moles of that compound. So you would use only the formula for NH3 to calculate the molar mass. To calculate M, multiply the molar mass of each element (atomic weight in g/mol) by its subscript and add the results.

What has a mass of 1 amu?

An atomic mass unit (symbolized AMU or amu) is defined as precisely 1/12 the mass of an atom of carbon-12. The carbon-12 (C-12) atom has six protons and six neutrons in its nucleus. In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass.
