Answer:
63.01284 g/mol
Explanation:
This compound is also known as Nitric Acid.
Convert grams HNO3 to moles or moles HNO3 to grams
Molecular weight calculation:
1.00794 + 14.0067 + 15.9994*3
Percent composition by element
Element Symbol Atomic Mass # of Atoms Mass Percent
Hydrogen H 1.00794 1 1.600%
Nitrogen N 14.0067 1 22.228%
Oxygen O 15.9994 3 76.172%
Answer is: <span>the objects potential energy is 24500 J.
</span>m(object) = 50 kg.
h(object) = 50 m.
g = 9,8 m/s².
E(object) = m·g·h.
E(object) = 50 kg · 9,8 m/s² · 50 m.
E(object) = 24500 N·m = 24500 J = 24,5 kJ.
g - <span>the acceleration of free fall.
mg - </span><span>weight of the object.</span>
In this situation, we can use the ideal gas equation which is PV = nRT
P = Pressure (atm)
V = Volume (L)
n = moles (mol)
R = constant (0.08206 atm-l/mol-K)
T = Temperature (K) ---> C + 273.15 = K
PV = nRT
n = PV/RT
= (7atm)(15L) / (0.08206 atm-l/mol-K)(23 + 273.15)
= 4.32 mol
Hope that helped!!!
