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.
What is the molecular mass of Br2 quizlet?
The molar mass of bromine is 79.90 g/mol.
What is Br2 percent composition?
What is the molar mass of bromine gas Br2?
159.808 g/mol
What is the molar mass of bromine gas Br2 in grams?
Is Br a bromine?
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 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.

What is the oxidation state of BR in Br2?
Br2 is the natural state for bromine so its valence (oxidation state) is 0.
Why is Br2 a liquid at STP?
4 ( because it takes more energy to break the intermolecular bonds in I₂. ) Which statement explains why Br2 is a liquid at STP and I2 is a solid at STP? … Molecules of Br2 have stronger intermolecular forces than molecules of I₂.
Why is Br2 a liquid and I2 a solid?
Whether a substance is a solid liquid or gas depends on the balance between the kinetic energies of the molecules and their intermolecular attractions. … It is only at temperatures between -7 °C and 59 °C that fluorine and chlorine are gases bromine is a solid and iodine is a solid.

Is bromine an orange?
Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water but alkanes cannot. … This has the effect of ‘saturating’ the molecule and will turn an alkene into an alkane.
Is bromine a liquid?
Bromine is a naturally occurring element that is a liquid at room temperature. It has a brownish-red color with a bleach-like odor and it dissolves in water.
Is bromine a salt?
Salt water pools are less irritating to your eyes and skin but still contain chlorine. … Bromine systems are more expensive for outdoor pools but reduce eye and skin irritation. Mineral systems are growing in popularity easy to maintain and reduce chlorine usage.
