Answer:
<h2>The answer is 1.48 L</h2>Explanation:
In order to find the original volume we use the same for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the original volume
From the question
P1 = 172 kPa = 172000 Pa
P2 = 85 kPa = 85000 Pa
V2 = 3 L
We have
We have the final answer as
<h3>1.48 L</h3>Hope this helps you
10g
Explanation:
Box 1, Mass of A = 10g
Box 2, Mass of B = 5g
Box 3, = 1A + 1B
Unknown:
Mass of B that would combine with mass of 20g of A
Solution:
Mass ratio of A to B:
= mass ratio
= mass ratio
The mass ratio of A to B = 2: 1
Now, number of B that will combine with 20g of A;
= mass ratio
=
Mass of B = 10g
10g of B would combine with 20g of A
