How do I find the density of sand particles in this question?
An experiment was performed in which an empty 100 mL graduated cylinder was weighed. It was weighed once again after it had been filled to the 10.0 mL mark with dry sand. A 10mL pipet was used to transfer 10.0 mL of methanol to the cylinder. Use the data (below) to find the density of dry sand, the density of methanol, and the density of sand particles.
Mass of cylinder plus wet sand 45.2613 g
Mass of cylinder plus dry sand 37.3488 g
Mass of empty cylinder 22.8317 g
Volume of dry sand 10.0 mL
Volume of sand + methanol 17.6 mL
Volume of methanol 10.00 mL
I was able to get the first two densities, but how do you find the density of sand particles?
@cattbarf:
That seems to me like it would be the way to find the density of dry sand, but I need to find the density of 'sand particles', which I don't completely understand myself.
Well, there are spaces between the sand particles ad the fluid occupies these spaces. If I were to use that assumption to calculate the density of sand particles, I'd have to say that the sand particles only occupy a volume of 7.6mL. They weigh the same as the dry particles, so use that mass to calculate the density.
However, if sand particles refers to sand+methanol, the use the weight of the wet sand (45.2613-22.8317)g and volume 17.6mL to calculate the density of the sand particles.
I'd do both calculations if I were you to be on the safe side.
Boston, Massachusetts Buying and Selling a Home with a Wet Basement
In the Massachusetts housing market, particularly in areas like Metrowest, North Shore, South Shore, Cambridge, and Boston, it’s becoming harder than ever to sell a home with a wet basement. And why wouldn’t it be? Basement water and humidity essentially ruins an entire floor of the home- destroying wood, drywall, paper, leather, furniture, fiberglass resins and backing, sports memorabilia, photographs, cloth, and anything else that contains organic material.
Business is Business
As it stands, the issue is a dire one for homeowners selling with a wet basement. Builder Magazine has found that 19% of home buyers won’t even look at a “fixer upperâ€, and even when they will look at it, you can be sure that it’s not their first choice over a home with a dry basement. When a home buyer does finally decide to make an offer, you can be sure that the cost will be 10-25% less than it would be if the basement was a dry one.
Investing with Basement Repair
However, there is hope. Of the 12 home buying red flags cited by RealtyTimes, such as the presence of lead paint or asbestos, foundation issues, or defective roofing, solving basement moisture is likely the easiest and most inexpensive to repair. A good wet basement repair contractor can provide a warranty that can be transferred to a new owner, and with a $200,000 home, it can pay back for itself by upwards of 400% of the cost of the job. A good contractor can install a basement drainage system and sump pump in one, or perhaps two, days.
Conclusions: If you have a basement flooding with groundwater, fix it before you buy it. Ideally, you should fix it right away, so you can enjoy a dry basement before you sell it. If you’re buying a home, take a second look at that wet basement fixer-upper. It’s quite a bargain!
