What else can I help you with?
If some of the gas bubbles escape the volumetric flask during the experiment atmosphere. Would the calculated molar mass of the gas be greater or less than the theoretical molecular value?
If gas bubbles escape the volumetric flask, the calculated molar mass of the gas will be less than the theoretical molecular value. This is because the number of moles of gas remaining in the flask will be underestimated, leading to a lower molar mass calculation.
What is the working volume in a 500ml shake flask?
The working volume in a 500ml shake flask is typically around 20-25% less than the total flask volume, so it would be around 375-400ml. This allows for proper aeration and mixing of the culture without overflowing during shaking.
What would happen to a spot of water soluble ink consisting of a single coloured dye if it were used in distillation?
During distillation, the water-soluble ink would be subjected to heat, causing the water component to evaporate first. The dye, being less volatile, would likely remain in the distillation flask as a residue. If the dye were to dissolve in the distillate (the evaporated water), it would typically not concentrate in the vapor phase, thus separating the dye from the water. Ultimately, the distilled water would be free of the dye, while the dye would remain in the original container.
Is the volume occupied by the gas in the flask approxmately the same greater or less than before it was heated?
Assuming the flask is sealed - the volume remains the same but the pressure increases
Why would a glass of cold water reach room temperature faster than a bucket of cold water?
It takes less time to cool or heat a galls of water because there is less water. If it was a spoon of water it would take less time than a bucket. It is all about amount.
If you cool a flask to -200degrise what would happen to the air?
I the flask was sealed, the air inside of the flask would take up less space and as a result, cause a drop in pressure inside the flask.

Why did the water rush into the erlenmeyer flask when it was submerged in the cold water?
1. When the flask was placed into the cold water, the colder air molecules in the flask move slower, putting out less pressure. With the decrease in air pressure inside the flask, the now greater pressure outside pushes water into the flask until the pressure inside equals the pressure outside.
If the lighter was wet after filling the flask and had some water on it for the second weighing would the calculated molar mass of the gas be greater or less than the theoretical molecular weight?
The calculated weight would be more due to the water molecules dding to the weight.
Experiment for which liquid freezes the fastest?
water because its less dense
Why did the ink rise up when the flask is immersed into a hot water?
When the flask is immersed into hot water, the ink molecules gain thermal energy causing them to move more rapidly. This increased movement disrupts the intermolecular forces holding the ink together, making it less dense and causing it to rise up in the flask.
What makes a type of glassware more or less accurate?
volumetric flask

What would happen Salt water being denser wants to sink below the fresh water what would happen If you add less salt to the water what effect would this have?
Adding any amount of salt to pure water will make it more dense than pure water, so the slightly less salty water will still want to sink, just not as quickly. It would be like dropping a bowling ball into a tank of water, then drilling out some of the ball and repeating the experiment. The ball would sink a little more slowly, but it would still sink.
What experiment could see if hot water evaporates faster than cold water?
Hot water need less energy to be evaporated than cold water.
What would happen to to Saturn if it were placed water?
Theoretically, the planet Saturn would float when placed in water because it has an average density that is less than the density of water. On the other hand, there is probably not enough water in the solar system to permit the experiment to be performed. If you choose not to consider the planet as a whole, the atmosphere would float on the water but the rocky core would sink like a stone.
Would the concentration be too high or too low if a small volume of the acid solution is spilled when you transfer it into the erlenmeyer flask?
The concentration would be too low because some of the acid solution was spilled, reducing the total volume and concentration of the solution in the Erlenmeyer flask. This would result in a less concentrated solution than intended.
