Answer:
w = 164.62 g
Explanation:
molarity of a solution is given as -
Molarity (M) = ( w / m ) / V ( in L)
where ,
m = molecular mass ,
w = given mass ,
V = volume of solution ,
From the question ,
M = 500 mM = 0.5 M
( since , 1 mM = 1 / 100 M)
As we know , the molecular mass of potassium ferricyanide = 329.24 g/ mol
V = vol.of solution = 1 L
w = ?
<u>To find the value of w , using the above formula , and putting the respected values , </u>
Molarity (M) = ( w / m ) / V ( in L)
0.5 = ( w / 329.24 ) / 1 L
w = 164.62 g
The time take for the train to travel 950 Km is 7.92 h
<h3>What is speed? </h3>
Speed is the distance travelled per unit. Mathematically, it can be expressed as:
Speed = distance / time
With the above formula, we can determine the time. Details below:
<h3>How to determine the time</h3>
The time taken for the train t travel 950 Km can be obtained as follow:
- Speed = 120 Km/h
- Distance = 950 Km
- Time =?
Speed = distance / time
120= 950 / time
Cross multiply
120 × time = 950
Divide both side by 120
Time = 950 / 120
Time = 7.92 h

Answer:
<h2>
The answer is $6.52.</h2>
Explanation:
Firstly, let's check out the given:
1. Sports Utility Vehicle's (Original SUV) avg gas mileage - 17.5 miles per gallon (mpg)
2. SUV's (Hybrid SUV) avg gas mileage - 21.5 miles per gallon (mpg)
3. Gas price - $2.59 per gallon
What is asked? How much would you save driving 237 miles in the hybrid SUV compared to the original SUV?
Next, you have to know how much gallons each car consumes upon driving 237 miles. You can do division in this step.
1. Original SUV = 237 miles ÷ 
= 13.54 gallons
2. Hybrid SUV = 237 miles ÷ 
= 11.02 gallons
Now that you know how much gallons each car consumes, you can now get the gas price for the gallons.
1. Original SUV = 13.54 gallons × $2.59 per gallon = $35.06
2. Hybrid SUV = 11.02 gallons × $2.59 per gallon = $28.54
In order to check the difference, you have to subtract.
- $35.06 - $28.54 = $6.52 (this is the amount of money that you can save driving 237 miles in the hybrid SUV compared with the original SUV)
GravitationL force is equal to the mass of the object multiplied by the acceleration due to gravity. Assuming that this object is on earth, the acceleration due to gravity is 9.8 m/s^2. Therefore, 10 kg multiplied by 9.8 m/s^2 is equal to 98 N for the gravitational force.
Therefore, the gravitational force acting on an object that has a mass of 10.0 kg (assuming this object is on earth) is 98 N.
