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

400 mL or 0.4 L
What percent of oxygen is present in your atmosphere?

How many liters is 40 percent oxygen?

What is the empirical formula of a compound that is 40 percent sulfure and 60 percent oxygen?
S2o3
What organ in the human body uses 40 percent of the oxygen in your blood?
The brain consumes 40% of the oxygen in your blood.
A mixture of gases with a pressure of 800.0 mm Hg contains 60 percent nitrogen and 40 percent oxygen by volume What is the partial pressure of oxygen in this mixture?

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.
What makes up about 40 percent of normal blood and transport oxygen to the body?
Red blood cells (corpuscles)
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.
