Explanation:
Given parameters:
Number of molecules of oxygen gas = 9.23 x 10¹⁹molecules
Unknown:
Volume of oxygen = ?
Solution:
Assuming the gas is at standard temperature and pressure conditions;
Volume of gas = number of moles x 22.4
we need to find the number of moles of the oxygen gas;
number of moles = ![\frac{number of particles}{6.02 x 10[tex]^{23}](https://tex.z-dn.net/?f=%5Cfrac%7Bnumber%20of%20particles%7D%7B6.02%20x%2010%5Btex%5D%5E%7B23%7D)
}[/tex]
Number of moles = ![\frac{9.23 x [tex]10^{19}](https://tex.z-dn.net/?f=%5Cfrac%7B9.23%20x%20%5Btex%5D10%5E%7B19%7D)
}{6.02 x 10
}[/tex]
Number of moles = 1.53 x 10⁻⁴moles
Volume of gas = 1.53 x 10⁻⁴ x 22.4 = 0.0034L

Answer:
482.4 kg
Explanation:
104 calorie = 435344 J
The 2.5% of this energy equals to
435344 * 0.0025 = 10883.6 J
If this energy is converted to work done on lifting a barbell by a distance of 2.3. By the formula of Work W = force * distance then the force he exerts on the barbell is
Assuming gravitational constant g = 9.81 m/s2 then the mass of the barbell is
m = 4732 / 9.81 = 482.4 kg
