What is nitrogen's atomic mass?
Millions of tons. !!!!! Nitrogen forms 79% of the world wide atmosphere. The total mass of the atmosphere is estimated to be 5.15 x 10^(18) kgs. [5,150,000,000,000,000,000 kgs]. So 79 % of this mass is 4.0685 x 10^(18) kgs of nitrgoen .
What is meant by the mass mass percent concentration of a solution?
This is (mass of solute) divided by (mass of total solution) expressed as a percentage. The solute is what you are dissolving into the solution. Example: you have 90 grams of water, and you add 10 grams of salt (sodium chloride). The water is the solvent, sodium chloride is the solute, and the solution is salt water. 90 grams + 10 grams = 100 grams (mass of total solution). (10 grams) / (100 grams) = 0.1 --> 10% mass mass percent concentration.
How do you find the mass percent mole fraction molality and molarity of a solution?
Mass percent = grams of solute/total grams of solution Mole fraction = mols component/total mols mix. Molarity = mols solute/L solution Molality = mols solute/kg solvent Hope this helps :)
What is the equation used to calculate percent by mass?
Percent by mass = (100) times (mass of the ingredient of interest) divided by (mass of the whole mixture)
What is the difference of percent of mass and percent of volume?
Percent of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.
