For hydrogen bromine 79.90 and again the unitsMoreSo we also have one bromine so we’ll add to the 1.01. For hydrogen bromine 79.90 and again the units are grams per mole. So when we add these two numbers together we get 80.91 in the units.
What is formula mass vs molar mass?
The key difference between formula mass and molar mass is that, the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula while molar mass is the mass in grams of 1 mol of substance.

How do you determine formula or 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 the molar mass of kno3?
101.1032 g/molPotassium nitrate / Molar mass
What is the molar mass of chlorine?
35.453 uChlorine / Atomic mass
What is meant by formula mass?
The formula mass of a substance is the sum of the average atomic masses of each atom represented in the chemical formula and is expressed in atomic mass units. The formula mass of a covalent compound is also called the molecular mass.
What is formula mass Class 11?
The formula mass of a molecule is the sum of the atomic weights of the atoms in the empirical formula of the compound. The formula weight) is the sum of the atomic weights of the atoms in the empirical formula of the compound Formula.
How do you determine mass?
What Is The Formula For Mass?
- mass=density×volume (m=ρV). Density is a measure of mass per unit of volume, so the mass of an object can be determined by multiplying density by volume.
- mass=force÷acceleration (m=F/a).
- mass=weight÷gravitational acceleration (m=W/g).
How do you calculate mass in chemistry?
MASS OF A SUBSTANCE = VOLUME X DENSITY.
What is the molar mass of Ca NO3 2?
164.1 g/mol.
Hence, the molar mass of Ca(NO3)2 is 164.1 g/mol.
What is the melting point of HBr?
HBr (aq) Molar mass: 80.91 g·mol −1 Appearance colorless/faint yellow liquid Odor: acrid Density: 1.49 g/cm 3 (48% w/w aq.) Melting point: −11 °C (12 °F; 262 K) (47–49% w/w aq.) Boiling point: 122 °C (252 °F; 395 K) at 700 mmHg (47–49% w/w aq.)
What is the pH of HBr?
What is the pH of HBr? Hydrobromic Acid or HBr, is a strong acid and will dissociate completely in water to H+ and Br-. For every mole of HBr, there will be 1 mole of H+, so the concentration of H+ will be the same as the concentration of HBr.
What substance has the highest molar mass?
Thus, we can conclude that polyethylene, a polymer of ethane has the highest molar mass.
What is the Lewis structure of HBr?
– The atoms are first connected by single bonds. – If t is the total number of electrons and n the number of single bonds, t-2n electrons remain to be placed. – Once all lone pairs are placed, atoms (especially the central atoms) may not have an octet of electrons.
