Answer:
gravitational force increases with mass and decreases with distance
Answer:
Explanation:
Hello!!
Please remember that density=mass/volume.
In this case, we have the same mass for the feathers and the gold (1 pound).
So, if the mass is the same for both we have:
Df*Vg=Dg*Vf where f means feathers and g means gold.
In this case we see density is inversely related to volume. Both materials have the same mass. So which one have a bigger volume?
For this take a pound of feathers and submerge in a known volume of water. Note the displacement. Do the same for a pound of gold. Whichever has the smaller displacement, has the greater density.
In this case, Gold has the greatest density.

Explanation:
The molar mass of Aluminium sulphite Al2(SO3)3.
Explanation:
To calculate the mass of the Aluminium Sulphite Al2(SO3)3
Two aluminium atoms: 2(26.98) + (32.07 + 48.00) 3
= 53.96 + (80.07) 3
=294.17 g/mol
1 mole = 6.022*10²³ particles
The mass of the element (m) = M * n
= 294.17 * 30.5
= 8,972.18 g
Thus the mass of the element in 30.5 grms of Aluminium sulphite is 8.972g.
