1 mole --------------- 6.02 x 10²³ atoms
( moles iron) -------- 5.0 x 10²⁵ atoms
( moles iron ) = 5.0 x 10²⁵ x 1 / 6.02 x 10²³
moles iron = 5.0 x 10²⁵ / 6.02 x 10²³
= 83.05 moles of iron
hope this helps!
Answer:
Explanation:
In this case, Gay-Lussac's law is used to compute the required temperature, as it relates pressure and temperature, by knowing that the atmospheric standard temperature is 25 °C, as follows:
Thus, the initial pressure is known as 14.7 psi and the initial temperature 25 °C, which correspond to the atmospheric conditions. Nonetheless, the pressure into the cooker, should be:
Since the 12.5 psi are above the atmospheric pressure. In such a way, the temperature inside the cooker turns out:
