As we know,

So, we can infer that :

Now, let's calculate the mass of gases in each case :
<h3>Case A : Hydrogen ~</h3>



or

<h3>Case B : Helium ~ </h3>



or

<h3>Case C : Nitrogen ~ </h3>



or

So, the arrangement of masses from least to greatest is :
- (1.) Hydrogen < (2.) Helium < (3.) Nitrogen
Answer:
g = 1.5
Step-by-step explanation:
g/3 - 0.9 = (-0.4)
Add 0.9
g/3 = (.9) + (-.04)
g/3 = (.5)
Multiply both sides by 3 to get G by itself
g = 1.5
Answer:
5/8
Step-by-step explanation:
i took the quiz
Remember, ab+ac=a(b+c)
undistribute the 14
14(l)+14(3a)=14(l+3a)
D is answer
