How do you find molecular mass?

Multiply the atomic weight of each element with the number of atoms of that particular element. Similarly do it for all the elements in the molecule or compound. Add up all the values obtained in the above step. Then add the unit as grams/mole you will get the molecular mass of the substance.

Is Br a bromine?

bromine (Br) chemical element a deep red noxious liquid and a member of the halogen elements or Group 17 (Group VIIa) of the periodic table.

Why Br2 is a liquid?

Bromine is a liquid because the intermolecular forces are strong enough so that it does not evaporate. Bromine forms diatomic molecules and Van der Waals interactions are sufficiently strong.

What is a molecule of bromine?

Bromine compound is a molecule formed when two bromine atoms combine together. Bromine (Br₂) is a red-brown liquid at ordinary temperature. … It is sold as salts or other compounds because pure bromine is expensive and difficult to produce. Bromine was discovered by French chemist Antoine J. Balard in 1826.

What is the molecular mass of CaCO3?

Calcium carbonate/Molar mass
The molar mass of CaCO3 is 100.0869 g/mol. We need to add the molar masses of calcium (40.078 g/mol) carbon (12.0107 g/mol) and three oxygen atoms…

How do you find the molar mass of C6H12O6?

i.e. mass of 1 mole of glucose C6H12O6 = (6 × 12.01 + 12 × 1.01 + 6 × 16.00) g = 180.18 g (using atomic weight data to 2 decimals) 1 mole of carbon atoms weighs 12.01 g and there are 6 moles of C atoms in 1 mole of glucose so the mass of carbon in 1 mole of glucose = 6 × 12.01 g = 72.06 g.

How do you find the molar mass of na2so4?

What reflects Avogadro’s number?
