<span>6.2 divided by the mass number of NO3 is 0.1 moles.</span>
The reaction equation is: CaF₂ + H₂SO₄ → 2HF + CaSO₄
The molar ratio between fluorite and hydrogen fluoride is 1 : 1.
The moles of fluorite supplied are:
Moles = 15 / 78.07 Moles = 0.200
The moles of hydrogen fluoride produced will be 0.2.Now, we may use the ideal gas equation to determine the temperature:
PV = nRT T = PV/nR
T = (875 * 8.63) / (0.2 * 62.36)
T = 605.45K
The temperature will be 331.85 °C which is required to store the gas in an 8.63-L container at 875 torr.

<u>Charge:</u>
An electron has a negative charge and a <em>n</em>eutron has a <em>n</em>eutral charge.
<u>Size:</u>
Electrons have a really small mass whereas the neutron has a mass of about 1 amu.
<u>Location:</u>
Neutrons are found in center of an atom, but electrons are around it.
<u>Number:</u>
The number of electrons and neutrons in atom varies.
It is a poly atomic anion because it has more than one atom and a negative charge
