How many moles are found in a 100.0-g sample of CuF2?
ivolga24 [154]
To determine the amount of a substance in units of moles from units of grams, we need to determine the molar mass of the substance. <span>The </span>molar mass<span> is the </span>mass<span> of a given chemical element or chemical compound (g) divided by the amount of substance (mol). For CuF2, the molar mass </span><span>101.543 g/mol. We calculate as follows:

100.0 g CuF2 ( 1 mol / 101.543 g) = 0.98 mol CuF2</span>

(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.
