How do you calculate molar mass?
Solutions
- The molar mass of silver is 107.87 g/mol.
- The molar mass of gold is 196.97 g/mol.
- The molar mass of sodium oxide is 61.98 g/mol: 2 (Na) + 1 (O) = 22.99 g/mol + 16 g/mol = 61.98 g/mol.
- The molar mass of calcium sulfide is 72.14 g/mol: 1 (Ca) + 1 (S) = 40.08 g/mol + 32.06 g/mol = 72.14 g/mol.
What is the formula to find molar mass?
What is the formula to find molar mass? The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol).To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.
How to find the molecular formula with molar mass?
It's easy to find the molecular mass of a compound with these steps:
- Determine the molecular formula of the molecule.
- Use the periodic table to determine the atomic mass of each element in the molecule.
- Multiply each element's atomic mass by the number of atoms of that element in the molecule. ...
- Add these values together for each different atom in the molecule.
How can you find molar mass?
- 0.5 moles (CO2) x 44g/mole = 22g
- 22g > 16g
- So 0.5moles of CO2

What is ERG 154?
Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. (ERG, 2016)

How far should you isolate a spill?
Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above. FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.
