Magnetic energy from the magnet applies a force to the compass needle causing it to move
Answer:

Explanation:
Hello,
In this case, since the work done at constant pressure as in isobaric process is computed by:

Thus, given the pressure, initial volume and work, the final volume is:

Whereas the pressure must be expressed in Pa as the work is given in J (Pa*m³):

And the volumes in m³:

Thus, the final volume turns out:

Best regards.
(g solute/g solution)*100 = % mass/mass
30 g / 400 * 100
0,075 * 100
= 7,5% w/w

Answer:
<h2>0.52 moles </h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula

where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have

We have the final answer as
<h3>0.52 moles</h3>
Hope this helps you
