Answer : The final concentration of the seawater is, 2.909 mole/L
Explanation :
Formula used for osmotic pressure :
where,
= osmotic pressure = 70.0 bar = 70 atm
R = solution constant = 0.0821 Latm/moleK
T= temperature of solution =
C = final concentration of seawater = ?
Now put all the given values in the above formula, we get the concentration of seawater.
Therefore, the final concentration of the seawater is, 2.909 mole/L
If the forces are equal and in opposite directions, the net force will equal zero.
Consider a tug-of-war team. If they are pulling with equal forces against each other, the red cloth on the rope will not move.
<em>F = ma </em>
The cloth is not moving, so <em>a = </em>0 and the net force <em>F = </em>0.
