A fracture Formation .
A matter is neither destroyed or created
Answer:
The SI base unit for amount of substance is the mole. 1 grams NaOH is equal to 0.025001806380511 mole.
Use the ideal gas law:
PV = nRT
so, T = PV / nR
n=0.5
V= 120 dm^3 = 120 L (1 dm^3 = 1 L)
R = 1/12
P = 15,000 Pa = 0.147 atm (1 pa = 9.86 10^{-6} )
Put the values:
T = PV / nR
T = (0.147) (120) / (0.5) (1/12)
T= 426 K
If your talking about mole. p
1 mole of water weighs 18 g
Therefore 0.5 mole of water weighs 9 g
According to Avagadro,
1 mol = 6.023 **10^23
atoms
So,
0.5 mol = 3.0115 **10^23
molecules of water
Each water molecule contains 2 hydrogen atoms .
Therefore
2** 3.00115**10^23
atoms of hydrogen are present in 9g of water
Answer:
The answer is
6.02⋅1023
