I have 3 chemistry problems that I am really struggling withIf you could answer any of them and show me how you came to the answer it would be a ton of help.1) In Europe, gasoline is solid by the literIf MrV's 1990 Honda Accord has a 14.0 gallon gas tank, how many liters of gas would it require? If the price of gas at the Speedway is $1.65 per gallon, what is the price per liter? How much will it cost to fill the tank completely?2) The approximate mass of the earth is 5.94 x 10^21 metric tonsIf the circumference of the Earth at the equator is approximately 25,000 miles, what is the approximate density of the earth in g/mL?3) A sheet of aluminum foil has a total area of 1,000 square feet and a mass of 3.636What is the thickness of the foil in millimeters?
1) In Europe, gasoline is solid by the literIf MrV's 1990 Honda Accord has a 14.0 gallon gas tank, how many liters of gas would it require? How much will it cost to fill the tank completely? 14.0 gal $1.65 / gallon $23.1 If the price of gas at the Speedway is $1.65 per gallon, what is the price per liter? ($1.65 / gallon) (1 gallon / 3.785 litres) $ 0.436 / litre 2) The approximate mass of the earth is 5.94 x 10^21 metric tonsIf the circumference of the Earth at the equator is approximately 25,000 miles, what is the approximate density of the earth in g/mL? (5.94 x 10^21 metric tons.) ( 1,000,000 grams / metric ton) 5.94 X 10^27 grams (25,000 miles) (609.3 meters / mile)(100 cm / meter) 1.523 X 10^6 cm volume of a sphere 4/3 pi r^3 volume (4/3) (3.14) (1.523 X 10^6 cm)^3 volume (4/3) (3.14) (3.53 X 10^18 cm^3 ) volume 1.48 X10^19 cm^3 density: ( 5.94 X 10^27 grams ) / 1.48 X10^19 cm^3 4,01 grams / cm3 aka 4.01 g/ml 3) A sheet of aluminum foil has a total area of 1,000 square feet and a mass of 3.636What is the thickness of the foil in millimeters? 1 foot has 30.48 cm so 1ft2 has (30.48 cm)^2 929 cm^2 1000 sq feet 929 cm^2 / sq ft 929,000 cm2 using the density of aluminum find volume, assuming you meant to say 3.636 grams 3.636 grams Al 1 ml / 2.70 grams 1.347ml which is also 1.347 cm3 (volume of 1.347 cm3) / (area of 929,000 cm2) 1.45 X10^-6 cm which is 1.45 X 10^-5 mm if however you meant to say and a mass of 3.636' kilograms then it volume would be 1347 cm3 its thickness would be 0.0145 mm or did you mean 1.000 square feet which is 929 cm2 email me with any changes
look everywhere and take a inspect to discover them! in case you lose or damage library books, you ought to pay a collection fee as a alternativeThis alternative fee has no connection with the fee of the books - I lost a $6 paperback from the library, already in very poor difficulty, and had to pay a $80 alternative fee.
There is no such thing as a thief proof security systemA security system is only ever any good as a deterrent to the opportunistIf a person is determined to steal they will find a way to do itSorry but it's the way of the world.
If a thief wants a book from the library he will get it.Alarm or bar code of notThe only things I can suggest are changing the postition of the check out desk so you can keep an eye on everyone walking outHaving someone at the door and as people walk out check there books to make sure they have checked them out.
In some cases it is misplacement or loss.In other cases it is theft.And rare books that expose Masonry or the occult are deliberately stolen from libraries all over the nation.And when an astute librarian catches it they will take those out of circulation and keep them as reference only books.
