Answer:
4 L
Explanation:
using general gas equation formula (in blue pen in attached image),
P1 = 1 atm
V1 = 2.5 L
T1 = 25°C
P2 = 0.5 atm
V2 = x
T2 = 20°C
making V2 subject of the formula (in red pen in attached image),
V2 = 1*2.5*20/25*0.5
= 50/12.5
= 4 L
have a great day!!!
Since the molecular weight of water is about 18 g/mol, you have about 1 mol of water. So, now we know that it takes approximately 46.2 kJ of heat energy to warm 18.02g of water from 25C to 100C and then to vaporize it into steam. Hopefully this helped!
Explanation:
The Question that I believe that is the most testable through scientific experimentation would be the first question.
Which gelatin takes longer to set. Gelatin with fruit or gelatin without fruit.
Answer:
135.027
Explanation:
Take the molar mass (from the periodic table) of Nitrogen (14.007) and Oxygen (15.999)
Add them together: 30.006 (this is 1 mole of NO)
30.006x4.5=135.027g
