High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical substances. The pre

ssures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000kPa (60,000,000Pa ). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of 5.10×10^8 , what is its running pressure in torr?

Answer:

3.83x10^6torr

Explanation:

Hello,

In this case, to perform the following unit conversion, it is convenient to know that 1 atm equals 101,325 Pa and 1 atm equals 760 torr:

5.10x10^8Pa*\frac{1atm}{101325Pa}*\frac{760torr}{1atm}=3.83x10^6torr

Best regards.

Its running pressure in torr would be :

5.10 x 10^8 pa  x 1kPa/1000 Pa x 760 / 101.325 kPa

= 5.10 x 10 ^5  x   76 x 10^-1  x 1.01325 x 10 ^-2

= 392.7375 x 10^2

= 3.927275 x 10^4

ope this helps

6. A silver ring has a mass of 5.25 grams also. Calculate the number of silver atoms present in the ring?
valentinak56 [21]
6. You must divide the mass by it’s molar mass to give you the total amount of moles within that piece. This will give you approx 0.05mol. You can now multiply this value by Avagadros constant which gives you 2.93 x 10^22 atoms. I would expect gold to have less atoms as it’s molar mass is higher than that of silvers, meaning that less atoms would be required to equal the same mass

Acid/base, precipitation, redox, or none:. 1. Ba(ClO3)2(s) ----> BaCl2(s) + 3O2(g). 2. CaO(s) +CO2(g) ----> CaCO3(s)
Aleks04 [339]
There are two equations given in the question. The type of reaction shown can be easily judged, if one takes a closer look at the equations.

1. <span>Ba(ClO3)2(s) ----> BaCl2(s) + 3O2(g) ------- Redox

2. </span><span>CaO(s) +CO2(g) ----> CaCO3(s) -------- None.

I hope that this is the answer that you were looking for and the answer has actually come to your desired help.</span>
