Answer:
The car travel 660 feet
Explanation:
First convert the Speed into <u>Feet/sec</u>
Speed of the car = 90 mi/hr
1 mi = 5280 ft
In 90 miles = 90 x 5280 = 475,200 feet
1 hr = 60 min
1 min = 60 sec
So ,
1 hr = 60 x 60 sec = 3600 sec
The speed is defined as the distance traveled by the object in unit time. The formula of speed is :
... given
Speed = 132 ft/sec
Now, time = 5 sec
Distance = 660 feet

moles of sodium thiosulfate solution = n
Molarity of the sodium thiosulfate solution = 0.150 M
Volume of sodium thiosulfate solution used = 0.890 mL = 0.00089 L
According to reaction [2], 2 moles of sodium thiosulfate reacts with 1 mol .
Then , 0.0001335 mol of sodium thiosulfate will reacts with:
of
Moles of = 0.00006675 mol
According to reaction [1], 1 mol of is obatnied from 1 mol of NaClO.
Then 0.00006675 mol of will be obtained from:
Mass of 0.00006675 mol of NaClO=
0.00006675 mol × 74.44 g/mol = 0.00496887 g
Mass of sample = 0.0854 g
Percentage of NaClO in sample:
