Translation:
In 1500 kg of air there are 0.8 carbon dioxide. How many ppm does the carbon dioxide sample correspond to?
Explanation:
Given parameters:
Mass of air = 1500kg
Mass of carbon dioxide= 0.8g
Unknown:
PPM of carbon dioxide in the sample = ?
SOLUTION :
The parts per million ppm is used to express dilute concentration of solutes. It simple means out of a million.
To express the answer in ppm, first convert into uniform units:
1500kg to g = ?
1kg = 1000g
1500kg = (1500 x 1000)g = 1500000g
To express as part per million:
x 1000000
x 1000000 = 0.533ppm

Hi there! Relative order is an advanced order type and a absolute date is the process of determing a age.
Answer:
Explanation:
Molarity is found by dividing the moles of solute by liters of solution.
We know the molarity is 1.2 M (mol\liter) and there are 2.3 liters of solution. Substitute the known values into the formula.
Since we are solving for x, we must isolate the variable. It is being divided by 2.3 and the inverse of division is multiplication. Multiply both sides by 2.3 liters.
In a solution with a molarity of 1.2 and 2.3 liters of solution, there are 2.76 moles.
B) land cools off much faster than water (creating a air region of high density above land and lower density above sea)
