Answer:
The answer is
<h2>11.18 cm³</h2>Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 123 g
density = 11.3 g/cm³
The volume is
We have the final answer as
<h3>11.18 cm³</h3>Hope this helps you
Answer:
D. 15.8atm
Explanation:
Given parameters:
Initial pressure = 13atm
Initial temperature = 34°C = 34 + 273 = 307K
Final temperature = 100°C = 100 + 273 = 373K
Unknown:
Final pressure = ?
Solution:
To solve this problem, we apply a derivation of the combined gas law taking the volume as a constant.
The expression is shown mathematically below;
=
P and T pressure and temperature values
1 and 2 are initial and final states
Insert the parameters and solve for T₂;
=
P₂ = 15.8atm
