The mass of the hydrogen gas in tank, given the data is 6.17 Kg
<h3>Data obtained from the question</h3>
- Pressure (P) = 500 Bar = 500 × 0.986923 = 493.4615 atm
- Temperature (T) = 25 °C = 25 + 273 = 298 K
- Volume (V) = 220 L
- Gas constant (R) = 0.0821 atm.L/Kmol
- Compressibility factor (z) = 1.45
- Molar mass of hydrogen gas = 2.016 g/mol
- Mass of hydrogen gas (m) =?
<h3>How to determine the mass </h3>
PV = znRT
Divid both sides by zRT
n = PV / zRT
but
mole (n) = mass (m) / molar mass (M)
Thus,
m / M = PV / zRT
m = MPV / zRT
m = (2.016 × 493.4615 × 220) / (1.45 × 0.0821 × 298)
m = 6169 g
Divide by 1000 to express in Kg
m = 6169 / 1000
m = 6.17 Kg

Explanation:
two moles sodium (45.98 g), one mole sulfur (32.06 g), and four moles oxygen (64.00 g) combine to form one mole of sodium sulfate (142.04 g).
Answer:
27.7 g
Explanation:
To solve this problem we use the definition of <em>molarity</em>:
From the problem we're given M = 2.5 M and volume = 0.100 L. We use the above formula and <u>calculate the required moles of calcium chloride</u> (CaCl₂):
Finally we use the<em> molecular weight</em> of calcium chloride to <u>calculate the required mass</u>:
- 0.25 moles CaCl₂ * 110.98 g/mol = 27.745 g CaCl₂
Rounding to the nearest tenth of a gram the answer is 27.7 g.
Answer:
The answer to your question is 14.3 %
Explanation:
Data
volume of ethanol = 50 ml
volume of water = 300 ml
volume percent = ?
Formula
Percent by volume = (volume of solute/volume of solution) x 100
Volume of solute = 50 ml
volume of solution = 300 + 50 = 350
Substitution
Percent by volume = (50/350) x 100
Simplification and result
<u>Percent by volume = 14.3 %</u>
Answer:
The physical and chemical properties of the product do not match the properties of the reactant.
Explanation:
Chemical change:
The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.
These changes are irreversible
These changes occur due to chemical reactions
These may not be observed with naked eye
Example:
Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood
Boiling of egg: that change the chemical composition of protein in the egg .
The reaction of Hydrogen and oxygen:
H 2 (g) + O 2 (g) -------------------------------------> 2H 2O (l)
The reaction between sugar and oxygen form a product which is different from the reactant that's why it indicate the occurrence of chemical reaction.
While in case of physical changes just state of matter are changed. Properties remain same.
