Answer:
I have no clue what the question is
Explanation:
According to the law of conservation of mass, it makes a generalized observation that there will occur no change in the mass of a substance even if it undergoes a chemical reaction.
Whereas this law of conservation does not explain any phenomenon of why this conservation of mass occurs.
Therefore, the given statements are classified as follows.
A) It was developed from past observations - Ture
B) It is subject to experimentation and revision - True
C) It explains why mass is conserved - False
D) It predicts future observations - True
Answer:
2.8 L
Explanation:
From the question given above, the following data were obtained:
Number of mole (n) = 0.109 mole
Pressure (P) = 0.98 atm
Temperature (T) = 307 K
Gas constant (R) = 0.0821 atm.L/Kmol
Volume (V) =?
The volume of the helium gas can be obtained by using the ideal gas equation as follow:
PV = nRT
0.98 × V = 0.109 × 0.0821 × 307
0.98 × V = 2.7473123
Divide both side by 0.98
V = 2.7473123 / 0.98
V = 2.8 L
Thus, the volume of the helium gas is 2.8 L.
