Your answer is C - Melting of a substance
If we assume the density of water= 1000 gm/lit.
so Volume = Mass / Density
Vol. = 524.24/1000
Vloume = 0.52424 liters
To determine the number of helium atoms present in a given mass of helium, we first convert the mass into number of moles by dividing the atomic mass of helium which is 4 grams per mole. Then, we multiply the Avogadro's number which <span>represents the number of
units in one mole of any substance. This has the value of 6.022 x 10^23 units /
mole. We do as follows:
537 kg He ( 1000 g / 1 kg ) ( 1 mol / 4 g ) ( 6.022 x 10^23 atom / mol ) = 8.08x10^28 atoms He</span>
1.4715 atm is the pressure of the sample 1.33 moles of fluorine gas that is contained in a 23.3 L container at 314 K.
What is an ideal equation?
The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas. The terms are: p = pressure, in pascals (Pa).
Given data:
Volume (V) = 23.3 L
Number of mole (n) = 1.33 moles
Temperature (T) = 314 K
Gas constant (R) = 0.821 atm.L/Kmol
Pressure (P) =?
The pressure inside the container can be obtained by using the ideal gas equation as illustrated below:
PV = nRT
P × 23.3 L = 1.33 moles × 0.0821 ×314 K
P = 1.4715 atm
Therefore, the pressure of the sample is 1.4715 atm.
