Number of moles = number of atoms/Avogadro's number
= (4.8x10^25)/(6.02x10^23)
=79.7 mol (3sf)
The answer is dilute. A dilute salt solution contains a small amount of salt with high water concentration while a concentrated salt solution has a large amount of salt with a lower water concentration. Salt is inorganic hence it is not monounsaturated, which is a term related to organic compounds. The salt is unable to dissolve anymore in a saturated salt solution, leaving the undissolved salt at the bottom and this is not the case here since we only have a small amount of salt.
When water hits a rock it freezes and breaks it apart.
200 moles of nitric acid.
Explanation:
We have the following chemical equation:
3 NO₂ + H₂O → 2 HNO₃+ NO
Taking in account the chemical equation, we devise the following reasoning:
if 3 moles of nitric dioxide (NO₂) produce 2 moles of nitric acid (HNO₃)
then 300 moles of nitric dioxide (NO₂) produce X moles of nitric acid (HNO₃)
X = (300 × 2) / 3 = 200 moles of nitric acid.

Answer:
0 °C
Explanation:
The melting point of a substance is the temperature at which it changes state from solid to liquid.
Different substance have different melting point.
The melting point of ice at 1 atmosphere of pressure is very to 0 °C this is also known as the ice point.
