In order to determine the effect of the change in temperature, we may apply Boyle's law. Boyle's law states that for a fixed amount of gas at a constant temperature, the pressure of the gas is inversely proportional to its volume.
Mathematically, this is:
PV = constant
Therefore, if the pressure of the gas is halved, the volume of the gas will be doubled.
Answer: The mass is 348.8g
Explanation:
We begin by using Avogadro's number to convert the number of molecules of Sodium Hydroxide to moles.
6.02 x 10∧23 molecules of NaOH -------> 1 mole of NaOH
∴ 5.25 x 10∧24 molecules of NaOH -------> 1/ 6.02 x 10∧23 x 5.25 x 10∧24 =
8.72moles.
Having found the number of moles, we then move from moles to gram by using the molar mass of NaOH (i.e the mass of 1 mole of NaOH).
1 mole of NaOH is equivalent to 40g (Molar Mass)
8.72 moles of NaOH would be equivalent to; 40/ 1 x 8.72 = 348.8g
The mass in 5.25 x 10∧24molecules of NaOH is 348.8g
The element can also be called gold-197. It has Mass number
is 197, atomic number is 79 and electrons 79, Atoms that have the same number
of protons but different number of neutrons. Isotopes have identical numbers of
protons and electrons.
The correct answer is oceanic crust, 80 km, Hope this helps let me know.
