Answer:
124225.91 g of Na₃PO₄
Explanation:
From the question given above, the following data were obtained:
Number of atoms of Na₃PO₄ = 4.56×10²⁶ atoms
Mass of Na₃PO₄ =?
From Avogadro's hypothesis,
6.02×10²³ atoms = 1 mole of Na₃PO₄
Next, we shall determine the mass of 1 mole of Na₃PO₄. This can be obtained as follow:
1 mole of Na₃PO₄ = (23×3) + 31 + (16×4)
= 69 + 31 + 64
= 164 g
Thus,
6.02×10²³ atoms = 164 g of Na₃PO₄
Finally, we shall determine the mass of Na₃PO₄ that contains 4.56×10²⁶ atoms. This can be obtained as follow:
6.02×10²³ atoms = 164 g of Na₃PO₄
Therefore,
4.56×10²⁶ atoms = (4.56×10²⁶ × 164)/6.02×10²³
4.56×10²⁶ atoms = 124225.91 g of Na₃PO₄
Therefore, 124225.91 g of Na₃PO₄ contains 4.56×10²⁶ atoms
<span>The form of energy related to measurement of kinetic energy is heat energy. Basically, thermal energy is related to the measurement of molecula kinetics of a substance. It is due to the thermoagitation of the partices of the substances, which keep on moving. </span>
1- metal and non metal
2- true
3- chlorine
The average kinetic energy of 1 mole of a gas at -32 degrees Celsius is:
3.80 x 103 J
The relationship between volume and temperature of a gas, when pressure and moles of a gas are held constant, is: V*T = k.
FALSE
The relationship between moles and volume, when pressure and temperature of a gas are held constant, is: V/n = k. We could say then, that:
If the moles of gas are tripled, the volume must also triple.
If the temperature and volume of a gas are held constant, an increase in pressure would most likely be caused by an increase in the number of moles of gas.
TRUE
If the vapor pressure of a liquid is less than the atmospheric pressure, the liquid will not boil.
