All chemist. weighs A cylinder Of compressed oxygen O2. And finds that it Has a mass of 102 7.8 gram. After some of the oxygen is used in an experiment. The cylinder has the mass of 102 3.2 grams.
To find the mass of the oxygen used in the experiment, we need to subtract the final mass of the cylinder from the initial mass of the cylinder.
Final mass of cylinder = 102.3.2 grams
Initial mass of cylinder = 102.7.8 grams
Mass of oxygen used = Initial mass - Final mass
= 102.7.8 grams - 102.3.2 grams
= 4.6 grams
Therefore, the mass of oxygen used in the experiment is 4.6 grams.
To find the mass of the oxygen used in the experiment, you need to subtract the final mass of the compressed oxygen cylinder from the initial mass of the cylinder.
Step 1: Subtract the final mass from the initial mass:
1027.8g - 1023.2g = 4.6g
So, the mass of the oxygen used in the experiment is 4.6 grams.
