Mass=5kg=5000g
Volume=50cm^3

$\\ \rm\longmapsto Density=\dfrac{Mass}{Volume}$

$\\ \rm\longmapsto Density=\dfrac{5000}{50}$

$\\ \rm\longmapsto Density=100g/cm^3$

How many mols are present in the a sample of silver nitrate which has<br> 5.3x10^24 molecules.

Westkost [7]

Answer: 5.3 x 10^24 formula units of silver nitrate is equivalent to 8.8 moles of silver nitrate. Silver nitrate is an ionic compound, therefore, its representative particle is called a "formula unit" instead of molecule. For every mole of a substance, we know that there are 6.022 x 10^23 representative units of that substance. The amount of particles in one mole of substance is called Avogadro's number.

Further Explanation:

We can convert from number of representative particles to moles using the formula:

$\boxed {no. \ of \ moles \ = \ ( given \ no. \ of \ particles) \ (\frac{1 \ mole}{\ 6.022 \ x 10^{23} particles})}$

For this problem, we can calculate the number of moles by plugging in the given values to the equation above,

$no. \ of \ moles \ = (5.3 \ x \ 10^{24} \ formula \ units \ AgNO_{3}) \ (\frac{1 \ mole \ AgNO_{3}}{6.022 \ x 10^{23} \ formula \ units AgNO_{3}}) \\\\\boxed {no. \ of moles \ AgNO_{3} \ = \ 8.8 \ moles}$

How a reaction between colorless substances can produce a colored precipitate

abruzzese [7]

A reaction between colorless substances can produce a colored precipitate by formation of new ionic compound.

<h3>What is an ionic compound?</h3>

An ionic compound is a compound that is made up of two elements, one metal and the other non metal, which are held together by an ionic bonding.

When reaction occurs between two colourless substances, colored precipitate results by formation of new ionic compound.
