The volume of the oxygen gas at standard temperature is 41.36 liters.
The given parameters;
- <em>initial volume of oxygen, V₁ = 45 L</em>
- <em>temperature of oxygen, T₁ = 24 ⁰C = 297 K</em>
- <em>standard temperature, T₂ = 0 ⁰C = 273 K</em>
<em />
The volume of the oxygen gas at standard temperature is determined by applying Charles law as shown below;
Thus, the volume of the oxygen gas at standard temperature is 41.36 L.

Answer:
Concentration of ammonia = 3M
Explanation:
The reaction for the question is a neutralization reaction between HCl and NH₃
The chemical equation for the reaction is given as
HCl + NH₃ → NH₄CL
1 : 1 1
Volume of HCl = 18.1ml = 0.0181L
Volume of NH₃ = 5ml= 0.005L
Molar concentration of HCl=0.8M
Molar Concentration of NH₃ =?
Number of moles(n)= Molar concentration × Volume
n = C × V
n of HCL= 0.8 × 0.0181
n = 0.01448moles
Since mole ration for the reaction from the balanced equation above is 1:1,
n of NH₃ = 0.01448
molar concentration (C) of NH₃ = n/v
C of NH₃ = 0.01448/0.005
C of NH₃=2.896
C OF NH₃ =3M
I think it is B. Earths magnetic feild
But i'm not sure.
Answer:
Because the rock is irregularly shaped, you used the displacement method to measure its volume. You used <u>calculations</u> to indirectly find the <u>density</u> of the objects.
