If a patient\'s blood pressure is 145 over 65 mmHg, what is it in atmospheres (atm)
kicyunya [14]

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!"

The mass defect for the formation of lithium-6 is 0.0343 g/mol. The binding energy for lithium-6 nuclei is ________ kJ/mol. Ente
Sholpan [36]

<u>Answer:</u> The binding energy for lithium-6 nuclei is 3.09 E+11

<u>Explanation:</u>

Binding energy is defined as the energy which holds the nucleus together. It is basically the product of mass defect and the square of the speed of light.

This energy is calculated by using Einstein's equation, which is:

E=\Delta mc^2

where,

E = Binding energy of the atom

Delta m = Mass defect = 0.0343g/mol = 0.0343\times 10^{-3}kg/mol     (Conversion factor: 1kg=10^3g )

c = speed of light = 3\times 10^8m/s

Putting values in above equation, we get:

E=0.0343\times 10^{-3}kg/mol\times (3\times 10^8m/s)^2

E=3.09\times 10^{14}J/mol=3.09\times 10^{11}kJ/mol     (Conversion factor: 1kJ=10^3J )

Hence, the binding energy for lithium-6 nuclei is 3.09 E+11

What is an extensive property that can be calculated?
padilas [110]

Answer: The property which depends on the quantity of the substance is called an extensive property. The free energy change for a reaction (Δ G) depends on the quantity of the substance and is therefore an extensive property. It shows the additive nature. The extensive property Δ G is easily calculated from the formula, ΔG = -nFE cell.

How many moles of 02 can be prepared from 6.75 moles of KCIO3 ?
Varvara68 [4.7K]

The equation for this question could be 2KClO_{3}→2KCl+3O_{2} .

so for 6.75 moles of KClO_{3}  *3 moles of O_{2}/2 moles of KClO_{3}

= 10.125
