Converting mmHg to atm is solved by division.
Example: Convert 745.0 to atm.
Solution- divide the mmHg value by the 760.0 mmHg / atm.
745 mmHg over 760.0 mmHg/atm
atm value is 0.980263
Now, I am a medical student and we have never had to convert a BP (blood pressure) to atm from mmHg, only ever kPA. SO, I am going to take a guess here and say that when you do the work to solve this, you are going to convert the Systolic (upper #) which is the 145. You should get 0.190789 and then convert the Diastolic (lower #) which is 65. You should get 0.08552632.
So your fraction so to speak should read, 0.190789/0.08552632 or 0.190789 over 0.08552632
(Just to note that is way to low of a BP, although it is irrelevant) Best wishes and good luck. "Remember, never just look for the right answer, look for why it is the right answer!"

Answer:
2 M
Explanation:
The equation for molarity is "M = moles/liters"
Potassium chloride's atomic mass is 74.55, meaning one mole of KCl is equal to 74.55g. In the equation, 298g of KCl is being used. To find out how many moles this is, multiply 298g of KCl by (1 mol/74.55g of KCl) to get 4.0 moles. Now you can use the equation for molarity.
M = 4.0 moles/2 Liters
Answer:
The stoichiometric coefficient for aluminum is 2
Explanation:
Step 1: Data given
Aluminum metal = Al(s)
aqueous iron(III) oxide = Fe2O3(s)
aqueous aluminum oxide = Al2O3(s)
iron metal = Fe(s)
Step 2: The unbalanced equation
Al(s) + Fe2O3(s) → Al2O3(s) + Fe(s)
Step 3: Balancing the equation
On the left side we have 1x Al , on the right we have 2x Al (in Al2O3). To balance the amount of Al on both sides, we have to multiply Al (on the left side) by 2.
2Al(s) + Fe2O3(s) → Al2O3(s) + Fe(s)
On the left side we have 2x Fe (in Fe2O3) , on the right we have 1x Fe. To balance the amount of Fe on both sides, we have to multiply Fe (on the right side) by 2. Now the equation is balanced.
2Al(s) + Fe2O3(s) → Al2O3(s) +2Fe(s)
The stoichiometric coefficient for aluminum is 2
