5 0
In Chemistry, the Periodic Table is the source of all knowledge. Look on it for the information you need.
B = 11 grams / mol
F = 19 grams / mol
This stuff has a formula of BF3.
The 3 only affects the F. There is 1 Boron and 3 florines. If you want a number to affect the Boron, use brackets. In this case, we don't.
BF3 = 11 + 3*19 = 11 + 57 = 68 grams / mol

Molar Mass BF3 = 68 grams /mol <<<< ==== answer

(2pts) During the Purification of Lactate Dehydrogenase (LDH) experiment, you will need 50ml of buffer A150. Buffer A150 is 30mM
torisob [31]

Answer:

The answer is "20 \ mL"

Explanation:

Given:

Molarity= number of moles

because it is 1 Liter

\to \frac{0.03\ moles}{1.5 moles}=0.02\ L= 20 \ mL \ of\  Tris\\\\

therefore,

it takes 20 mL of Tris.

\to \frac{0.150 \ moles}{5\ moles} =0.03\ L\\\\

                     = 30 \ mL \ of\ Nacl

So, take 20 \ mL\ of\ NaCl.
