The buoyancy of an object is dictated by its density. So let us calculate for density, where:density = mass / volume
Calculate the volume first of a solid cube:volume = (6 cm)^3 = 216 cm^3 = 216 mL
Therefore density is:density = 270 g / 216 mLdensity = 1.25 g / mL
Therefore this object will float in the layer in which the density is more than 1.25 g / mL.

The number of moles hydrogen produced when 6 moles of sodium are used is calculated as below
2Na + 2H2O = 2NaOH +H2
by use of mole ratio between Na to H2 which is 2:1 the moles of H2 is therefore
= 6 x1/2 = 3 moles of H2
Answer:
The molecular formula of the given compound is C6H12O6, which is also called Glucose.
Explanation:
The molar mass of glucose is 180.18.
Answer: energy=mgh 55*9.8*10.8= 5821.2 J <--- this can't be wrong, there's no other way to solve for it. set the potential energy equal to kinetic energy: 5821.2= 1/2...
