Assuming ideality:
PV=nRT
Pv= (mass/molarmass)RT
Solve for the mass :-)

The formula for iron (II) sulfate hexahydrate
FeH12O10S
Answer:
D) 373 mm Hg.
Explanation:
We can solve this problem by keeping in mind<em> Dalton's law of partial pressures</em>, which states that the total pressure of a mixture of gases is equal to the sum of each gas' partial pressures. In other words, for this case:
- Total Pressure = Ne Pressure + CO₂ Pressure + O₂ Pressure + H₂ Pressure
- 1245 mm Hg = Ne Pressure + 145 mm Hg + 228 mm Hg + 499 mm Hg
The answer is option D) 373 mm Hg.
<h2>Decomposition</h2>
Explanation:
A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product.
Since there is only one reactant and it is broken into smaller components,
it is not a synthesis reaction.
A decomposition reaction is a type of chemical reaction in which one reactant yields two or more products.
Since in our question,there is one reactant and it is broken to yield two products,it is a decomposition reaction.
