Calculate the number of moles 3.15 g of HNO3 19.3 g of NaCl 21.25 g of NaNO3

Answers

The number of moles:
3.15g of $HNO_(3)$
1 mole of $HNO_(3)$ - 63g.
x moles of $HNO_(3)$ - 3.15g
$x=(1\ mole*3.15g)/(63g)=(3.15)/(63)=0.05\ mole$

The number of moles:
19.3 g of NaCl
1 mole of NaCl- 58.44g.
x moles of NaCl- 19.3g.
$x=(1\ mole*19.3g)/(58.44g)=(19.3)/(58.44)=0.33\ mole$

The number of moles:
21.25 g of $NaNO_(3)$
1 mole of $NaNO_(3)$ - 85g.
x moles of $NaNO_(3)$ - 21.25g.
$x=(1\ mole*21.25g)/(85g)=(21.25)/(85)=0.25\ mole$

Compare the arrangements of individual particles in solids, liquids, and gases

Answers

In a gas, the particles are evenly spaced out and not in any particular order. There is no regular arrangement of liquid next to one another. Solids are regularly arranged and closely packed.

What are solids, liquids, and gases?

They can be compressed a lot (particles are widely spaced). Matter exists in three different states: solid, liquid, and gas.

By examining the configuration of their particles, it is possible to understand why they have various qualities.

A solid is a condition of matter that, even when unconstrained, keeps its shape and density.

A liquid is a nearly incompressible fluid with a (almost) constant volume regardless of pressure that adapts to the shape of its container.

A sample of matter that assumes the shape of the container it is stored in and develops a consistent density inside the container is referred to as a gas.

Therefore, the arrangements of individual particles in solids, liquids, and gases is different.

Solids - particles are very close together (highest density on the list)
Liquids - the particles slide past one another
Gases - particles bounce off of surroundings and the same particles of the gas
