Answer:
The boiling point of milk is close to the boiling point of water, which is 100 degrees C, or 212 degrees F at sea level, but milk contains additional molecules, so its boiling point is slightly higher.
Explanation:
The mass of water in the tank, given the data from the question is 549594 g
<h3> Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation:
Mole = mass / molar mass
<h3>How to determine the mass of water in the tank</h3>
From the question given above, the following data were obtained:
- Mole of water = 30533 moles
- Molar mass of water = 18 g/mol
- Mass of water = ?
The mass of the water can be obtained as follow:
Mass = mole × molar mass
Mass of water = 30533 × 18
Mass of water = 549594 g

Explanation:
Carbon atoms are found in hydrocarbons, naturally occurring compound with carbon and hydrogen, but there are molecules in nature that contain beside carbon and hydrogen, oxygen and nitrogen too. In this compounds there are carbon-oxygen and carbon-nitrogen covalent bonds.
Bellow you may see the chemical structure of adrenaline, a hormon found in the human body, were the oxygen (red) and nitrogen (blue) are bonded to carbon.

Answer:
Number of moles = 1.97 mol
Explanation:
Given data;
Number of moles of I₂ = ?
Mass = 500.0 g
Solution:
Number of moles = mass/ molar mass
Molar mass of I₂ = 253.8 g/mol
Number of moles = 500 g / 253.8 g/mol
Number of moles = 1.97 mol
