Answer:
The mass of CO in 12,000 Liters of air is .
Explanation:
The ppm is the amount of solute (in milligrams) present in one Liter of a solvent. It is also known as parts-per million.
To calculate the ppm of oxygen in sea water, we use the equation:
The ppm concentration of CO = 10 ppm
Mass of CO = m
Volume of air = 12,000 L
The mass of CO in 12,000 Liters of air is .
The compound : C₄₀H₄₄N₄O
<h3>Further explanation</h3>The empirical formula is the smallest comparison of atoms of compound =mole ratio of the components
The principle of determining empirical formula
• Determine the mass ratio of the constituent elements of the compound.
• Determine the mole ratio by dividing the percentage by the atomic mass
The mol ratio of composition : C : H : N : O
Answer:
<h2>12.38 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
m is the mass
v is the volume
