Use PV =nRT. Rearrange it to n = PV/RT.
P = 202.6 kPa
V = 4.0L
R = 8.314 kPa*L/mol*K
T = 127 °C + 273 = 400 K
Plug it in and solve. I got 0.24 moles of H2.
Answer:
Percent composition tells you which types of atoms (elements) are present in a molecule and their levels. Percent composition can also tell you about the different elements present in an ionic compound as well.
Heat is a form of energy. if the system absorbs heat/ energy it is endo thermic if it releases heat or energy it is eothermic
Answer:
0.484 mole
Explanation:
1 mole of glucose reacts with 6 moles of O2, producing :
6 moles of CO2
6 moles of H2O
678 kcal
Using rule of three you have:
1 mole of glucose -> 678 kcal
x mole of glucose -> 328 kcal
x = 328/678 * 1 =0.484 mole
