To do this, you need to know the atomic weight of the element you're dealing with, found on any Periodic Table. The atomic weight is the mass in grams of the element in one mole - this will provide you with a conversion factor. So take the measurement in grams and divide it by the atomic weight to convert to moles. Really what you're doing is multiplying the number by 1 mole, and dividing it by the equivalent of one mole, the atomic weight. That's the thought process behind unit analysis and how you get your "units to cancel".
In this case, the answer is about .25 moles B.
To determine how many liters of oxygen is in a 40% concentration, you would need to know the total volume of the substance in question. Then, you would multiply the percentage (40%) by the total volume to find the volume of oxygen.
If a substance is 28% oxygen, it means that 28% of the total substance is oxygen. To find the amount of oxygen in liters, you would need to know the total volume of the substance. Without this information, it is not possible to determine the exact amount of oxygen in liters.
Human lungs are 2 liters in volume by average. So... Average breath rate is 12 breaths per minute. In one minute the patient would take in 24 liters of air. You are supplying 2 liters of pure oxygen + 4.8 liters from air (20% of the 24 liters (Percent oxygen in dry air)) = 6.8 liters of Oxygen per minute. 6.8 liters oxygen / 24 liters intake = 28.3% Oxygen or you can look at the table given by the books at http://www.fpnotebook.com/ER/Procedure/LwFlwOxygn.htm Nasal Cannula, Flow 0 liters per minute: 21% (Room Air), Flow 2 liters per minute: 29% But I like the mathematical method. That's just me!
The percent by mass of oxygen in N2O4 is 69,56 %.
4 liters of oxygen is 100% oxygen because the volume is entirely filled with oxygen.
The mass of 4.38 liters of oxygen is 6,259 g.
To determine how many liters of oxygen represents 40 percent, you need to know the total volume of the mixture. For example, if you have 100 liters of gas, then 40 percent of that would be 40 liters of oxygen. Thus, the specific volume of oxygen depends on the total volume you’re considering.

Convert 40% oxygen to liters
To determine how many liters of oxygen is in a 40% concentration, you would need to know the total volume of the substance in question. Then, you would multiply the percentage (40%) by the total volume to find the volume of oxygen.
The density of a substance is equal to its mass divided by its volume. To calculate the density of oxygen in this case, we need to divide its mass by its volume. So, the density of 10 liters of oxygen with a mass of 0.014 would be 0.0014 g/mL.
The conversion from grams to liters depends on the density of the substance. To convert 40 grams to liters, you would need to know the density of the specific material. The formula for this conversion is: volume (liters) = mass (grams) / density (grams per liter).
1cm3=1ml40cm3=40ml=0.04l
40 liters = 40 000 cc
Magnesium oxide is a solid, not measured in litres.
The atomic mass of hydroxide (rounding) is 17.008 atomic mass of oxygen 16.00 + atomic mass of hydrogen 1.008
The weight of water is approximately 8.34 pounds per gallon. Since there are roughly 3.785 liters in a gallon, 40 liters of water would be equivalent to about 10.57 gallons. Multiplying 10.57 gallons by 8.34 pounds per gallon gives us a weight of approximately 88.39 pounds for 40 liters of water.
