Answer:
a. 2.49
Explanation:
Molar mass of HCl= 36.46 g
So, no. of moles=418.8/36.46=11.48
Molality= no. of moles/mass of solvent= 11.48/4.62= 2.49
The F is 2.980 x 104 N gravity Gm1 is 2523 kg m₂ is 5.68 x 1026 kg and radius 54,364 km and height is 108,728 km.
<h3>What is gravity?</h3>
Gravity is the amount of force that is produced by the earth to attract the object toward the surface and it doubles if the mass is double.
The height of Saturn is the duble of the radius of the given radius of 54,364 km of the planet Saturn which is 108,728 km.
Therefore, F is 2.980 x 104 N gravity Gm1 is 2523 kg m₂ is 5.68 x 1026 kg and radius 54,364 km and hight is 108,728 km.
