6 litres of 50% + 4 litres of 25%
40%% rate:= 51.2/128 * 100%= 0.40 * 100%= 40%
40%=30x .4=30x .4/30 = .01333333333333333333333333333333333333333333333333333333333333
400 mL or 0.4 L
40/50 reduces to 4/5 which would be 80 percent thus making it a B
40 percent
Red blood cells make up about 40 percent of normal blood and are responsible for transporting oxygen to the body tissues. These cells contain hemoglobin, a protein that binds to oxygen and carries it to various parts of the body.
The empirical formula of the compound with 40% sulfur and 60% oxygen is SO3 (sulfur trioxide). The ratio of sulfur to oxygen in the compound is 1:3, which simplifies to SO3.
The brain is the organ that uses about 20% of the oxygen in your blood.
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.
no
makes 40% oxygen than lower altitude
15% + 25% = 40%
=0.142857.. of the original volume.
We can't tell. What's the other 90 percent? If you meant 40/60 instead... the mass of sulfur is twice that of oxygen, so a mass ratio of 40:60 is equivalent to an atom ratio of 1:3. The empirical formula would be SO3.
actually we dont mix nitrogen nor oxygen we use normal fresh air. The normal Air is 21% oxygen + 78% Nitrogen + 1% others. As humans more oxygen can be toxic for us especially underwater. However, in some cases "Like with Nitrox" we add more oxygen to make the percentage up to 40%, but this require specific training and certification.
In C2H4O2 (acetic acid), there are two oxygen atoms. To find the percentage of oxygen in acetic acid, we calculate the molar mass of the oxygen atoms and divide it by the molar mass of the whole compound, then multiply by 100 to get the percentage. This results in a percentage of approximately 40% oxygen in acetic acid.
