A mole of water molecules would just about fill a
Strike441 [17]

Answer:

B. tablespoon

Explanation:

Considering the question given, a mole of water is small compare to the options given from the question aside the table spoon.

A mole of water is just 18g and that's equivalent to 18 mL.

18 mL of water will fill a table spoon but not a cup which is about 237mL. The wheel barrow and gallon bucket have larger volumes of which 18 mL of water will never fill them.

So, a mole of water can successfully fill a table spoon.

A cork has weight mg and density 25% of water’s density. A string is tied around the cork and attached to the bottom of a water-
yuradex [85]

Answer:

Explanation:

Given

Density of Cork \rho _c=0.25\rho _{water}

Considering V be the volume of Cork

Buoyant Force will be acting Upward and Weight is acting Downward along with T

Since density of water is more than cork therefore Cork will try to escape out of water but due to tension it will not

we can write as

\rho _{water}Vg-\rho _Cvg-T=0

where T=tension

Thus Tension T is

T=Vg(\rho _{water}-\rho _c)

Taking \rho _c common

T=\rho _cVg(\frac{\rho _{water}}{\rho _c}-1)    

T=mg(\frac{\rho _{water}}{\rho _c}-1)

T=mg(4-1)

T=3mg
