How much does 5 gallons of water weigh?Water:Water is one of the most important chemicals for life. It helps cool down animals and plants. It is also important because it serves as a medium for chemical reactions.Answer and Explanation: ...
On the other hand, the concentration of 962 mg/L tells you exactly how much salt to weigh out when making the solution. This is a prime example of why knowing how to convert from mmol/L to mg/L (and visa versa) can be helpful in the lab. References Chemistry, LibreTexts: 16.8: ...
How much does a 100 ml beaker weigh? If I made a 4.97 M solution with 2.16 mL of solute, what is the mol of volume, in liters? How do you solve gas stoichiometry problems? How do you convert liters to moles? For example, 75.2 L SO2 = moles ...
Step 1.Weigh the amount of solute (the compound being dissolved) in grams. Then determine how many grams are in a mole of the solute. There are 40 g per mole in sodium hydroxide (NaOH). Therefore, 20 g of NaOH would equal 0.50 mol of NaOH. The equation looks like this: mol NaOH ...
- weigh the dry nail before the experiment - immerse the nail in the solution for a given time - clean off any non-steel stuff, rinse and dry the nail - weigh the nail to see how much mass was lost, i.e., how much corrosion occurred. Good luck. Regards, Ted Mooney, P.E. Str...
to allow them to get closer to shelves and move more easily in enclosed spaces. Not exactly the kind of thing that human beings struggle all that much with, but then we also come with all those pesky human rights and mental health requirements. Digit, on the other hand, really does seem...
they weigh out a specific mass of saltwater and transfer it to a graduated cylinder to determine the volume. They find the density by taking the mass divided by the volume. They repeat this experiment multiple times and average their results. The student does not dry the graduated cylinder c...
I always check the pH of the soap, just to make sure I didn't make a mistake and add too much lye. I use pH test strips I bought dirt cheap on Ebay. Here I have put a few drops of water on one of the bars and smeared it around with my finger to dissolve some of the soap...
A good way to check to see if a soap is cured is to weigh the soap. As I showed in the graph above, soaps will generally lose the majority of their weight in the first 30 days. After that point, they don’t generally lose much weight. ...
** You can often find pure lye with no additional plumbing/drain additives in the drain cleaner section of a mom n’ pop hardware store. Lye is a naturally occurring substance that can be made by burning hardwoods and boiling the ashes, but it’s much easier to just buy. If you don’...
