Three blocks of the same mass are placed in front of you. Block A has a volume of
Ivan

Given :

Three block of same mass name A , B and C .

Sides of block A , B and C is 3.0 cm , 5.0 cm and 10.0 cm .

To Find :

Which block has the higher  density .

Solution :

We know , density \rho is given by :

\rho=\dfrac{M}{V}   ......1 )

Here , V is volume .

Now , volume V for cube is given :

V=a^3    .......2 )

(  Here , a is the side of cube )

Now ,form equation 1 we can see if mass remains constant then density decrease with increase in volume.

Therefore , cube with minimum side will have higher density , in this case it is 3 cm block .

Hence , this is the required solution .

Identify the relative molar amounts of the species in 0.10 M NaBr(aq). Br-, OH-, H2O, H3O+, NaBr, Na+
laila [671]
NaBr < H3O+1 = OH-1 < Na^+1 = Br^-1 < H2O 

<span>Least is NaBr (100% dissolved so no NaBr remains, only Na^+1 and Br^-1 </span>
<span>H2O yields 10^-7 M H3O^+1 and 10^-7 M OH^-1 (Kw = 1x10^-14 = [H3O+][OH-] </span>
<span>Na^+1 and Br^-1 will bothe be 0.1 M </span>
<span>H2O is slightly less that 1000 g / L in a 0.1 M NaBr solution, so its concentration is about 55.5 M</span>
