What is greater 50 percent of 40 or 40 percent of 50?
they are both equal
A chemist has one solution which is 50 percent acid and a second solution which is 25 percent acid how much of each should be mixed to make a 10 liters of a 40 percent acid solution?
6 litres of 50% + 4 litres of 25%
What percent of 128 is 51.2?
40%% rate:= 51.2/128 * 100%= 0.40 * 100%= 40%
If 40 percent equals to x30 what is the value of x?
40%=30x .4=30x .4/30 = .01333333333333333333333333333333333333333333333333333333333333
What is 40 percent of 1 liter?
400 mL or 0.4 L
What percent of oxygen is present in your atmosphere?
40 percent
What makes up about 40 percent of normal blood and transport oxygen to the body?
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.
What is the empirical formula of a compound that is 40 percent sulfure and 60 percent oxygen?
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.
What organ in the human body uses 40 percent of the oxygen in your blood?
The brain is the organ that uses about 20% of the oxygen in your blood.
How many liters is 40 percent oxygen?
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.
Is good soil 40 percent minerals 23 percent water 23 percent air 7 percent organic and 8 percent living material?
no
What does altitude do to the air pressure?
makes 40% oxygen than lower altitude
What does fifteen percent and twenty five percent make when you add them?
15% + 25% = 40%
How much liquid to add to make 40 percent to 35 percent?
=0.142857.. of the original volume.
What is the empirical formula of a compound that is 4 percent sulfur and 6 percent oxygen by weight?
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.
Why do you mix nitrogen with air when scuba diving?
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.
What is te percent of oxygen in C2H4O2?
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.
