table 3.7 in prentice hall chemistry That's going to depend on the pressure of the sample
as well as its temperature.
The density of air is 1.20 g/L. Use the mass formula (density x volume) to get your answer. 1.20 g/L x 5L equals 6g. mass=6g

mass Fe * Specific heat Fe* T=Q Q/( Specific Heat water*mass water)= temp change of water so... 4kg(.450 kJ/kg*C)(250C)= 3kg(4.184)T T=35.85 C That help?
Question makes no sense - unanswerable. Nothing changes mass when heated or cooled.
There is not enough information in this problem to answer the question. You must know the mass of the iron to find the amount of joules used to heat the iron.
0.52 mol.
A cubic centimeter of water at 4 degrees Celsius should be equal in mass to 1 gram
Liters measure volume. Grams are a measure of mass, degrees Celsius are a measure of temperature, and meters are a measure of length.
1kg = 1000g ice will have volume: Density = mass /volume Volume = mass / density Volume = 1000/0.92 Volume = 1,086.95ml = 1,087ml 1,087 ml = 1.087 liters.
Kilograms and Kelvin (or degrees Celsius).
exactly three over sixty-five million pounds or probably maybe in a book on a page that's in my locker. on like some chart. 3.7 i believe.
Due to more volume mass, it will take longer, but the 2 liters with double mass will eventually heat up the same 10 FIVE degrees with the same energy amount.
no it isn't
1.0 gramme

Further information - pressure - is required before this question can be answered.
8.8kg...i guessed
Aproximately 4 grams of potassium chlorate will dissolve in 50 g of water at 20 degrees celsius.
19 050 kilograms
