A scooter maintains a pace of 1.45 minutes per mile, with fuel economy of 85 miles per gallon. How many seconds can it travel on
vlada-n [284]

Answer:

281s

Explanation:

Given parameters:

Speed of the scooter  = 1.45min per mile

Fuel economy of engine  = 85miles per gallon

Quantity of fuel  = 145mL

Unknown:

Time of travel with the volume of fuel given  = ?

Solution:

To solve this problem, we need to find the distance the fuel will last.

 Rate of fuel consumption by the engine  = 85miles per gallon

Convert 145mL to gallons;

                3785.41mL  = 1 gallon

               145mL will therefore give \frac{145}{3785.41}    = 0.038gallons

So;

   Distance covered  = 85miles per gallon  x 0.038gallons  = 3.23miles

From;

             Rate of travel  = \frac{time }{distance}  

       Time  = rate of travel x distance  = 1.45 minutes per mile x  3.23miles

     Time  = 4.7min

             1 min  = 60s

            4.7min  = 4.7 x 60 = 281s

Using the periodic table in your textbook, calculate the molar mass of paraffin (C46H92O2).
ArbitrLikvidat [17]

Answer:

677.39 g/mol

Explanation:

Step 1: Find molar masses of elements

Carbon (C) - 12.01 g/mol

Hydrogen (H) - 1.01 g/mol

Oxygen (O) - 16.00 g/mol

Step 2: Multiply the amount present

12.01 g/mol · 46 = 552.46 g/mol

1.01 g/mol · 92 = 92.92 g/mol

16.00 g/mol · 2 = 32.00 g/mol

Step 3: Add up all the molar masses to find compound molar mass

552.46 g/mol + 92.92 g/mol + 32.00 g/mol = 677.39 g/mol
