<span>You can work out the following:
Mass = Density x Volume
Density = Mass Ă· Volume
Volume = Mass Ă· Density
The density of gold is 0.670205 oz/cm^3
The volume is length x width x depth = 7*3*2 = 42
The answer is Mass = 0.670205 x 42 = 281 ounces</span>

RFM 24 RFM 95
moles 2.708 moles 2.708
Explanation:
mass of MgCl = 257.26 grams
Beacause of lack of force in all three scenarios.
In scenario one there’s two forces acting in the bottle atmospheric pressure and gravity.Gravity keeps the ball at the lowest pointwithout force resisting it.
Umber two there’s no other force greater than gravity that would cause movement to the apple..
And number three there are isn’t any force acting in the rubber band greater than the elastic force to make it stretch
Hope this helps and mark as brainliest if you thought it was most helpful :)
