It would be 2336.2344 Joules
Didn't know how many decimals you wanted, so I put them all
I believe it would be the last one because you can use the molar mass of HCl to find the number of moles, then use Avogadro’s number to find the number of atoms
Hope this helps!
Answer:
Number 1
Explanation:
O The ice at 0 degrees is warmer than the ice at -30 degrees.
Answer:
Mass = 99.2 g
Explanation:
Given data:
Volume of oxygen = 15 L
Mass of oxygen = ?
Pressure of oxygen = 75 psi ( 75/14.696 = 5.10 atm)
Temperature of oxygen = 28°C (28+273 = 301 K)
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
n = PV/RT
n = 5.10 atm× 15 L / 0.0821 atm.L/ mol.K × 301 K
n = 76.5 atm.L/24.71 atm.L/ mol
n = 3.1 mol
mass of oxygen:
Mass = number of moles × molar mass
Mass = 3.1 mol × 32 g/mol
Mass = 99.2 g
