Answer:
The new volume of gas would be 30 L.
Explanation:
This is an example of a Combined Gas Laws problem.
Answer:
3 g/mL
Explanation:
We know that the density of an object can be measured by dividing its mass (g) to its volume (mL).
Formula
D=m/v
Given data:
Mass= 45 g
Volume= 15 mL
Now we will put the values in formula:
D=45 g/ 15 mL= 3 g/mL
There are only 2 atoms in an Oxygen molecule
