First we must find the molar mass of NaCl. We find the atomic mass of sodium and chlorine and add them:
Na: 22.9898
Cl: 35.453
22.9898 + 35.453 = 58.4428g/mol
The we find the number of mols contained in 400mg of NaCl:
.4g / 58.4428g/mol
.0068443 mol
Since 100mL is a tenth of a liter we can multiple the number of mols by ten:
.068443 mol/L</span>
In a gas, the partcles are very far apart and loose.

Everyday Examples of Convection
boiling water - When water boils, the heat passes from the burner into the pot, heating the water at the bottom. This hot water rises and cooler water moves down to replace it, causing a circular motion.
Explanation:
Answer:
The amount of mass and matter in all the transformations of the clay ball will remain the same or constant
Explanation:
From the law of conservation of mass we have, for an enclosed system to and from which there is no transfer of matter or energy, mass cannot be created nor destroyed, and remains constant at the given value, but the matter which make up the mass can be changed into different forms
Therefore, the clay ball can be transformed into different shapes and will still posses the same initial mass before the transformation, provided there are no transfer of matter or energy from the clay ball system.
