<span>The mass (in grams) of 8.45 x 10^23 molecules of dextrose is 252.798g Working: Mw. dextrose is 180.16 g/mol therefore 180.16 grams dextrose = 1 mole therefore 180.16 grams dextrose= 6.022x10^23 molecules (Avogadro's number) We have 8.45 x 10^23 molecules of dextrose. Therefore, (180.16 divided by 6.022x10^23) times 8.45x10^23 gives the mass (in grams) of 8.45 x 10^23 molecules of dextrose; 252.798.</span>

The decomposition of acetaldehyde is a second order reaction with a rate constant of 4.71 10−8 L/mol/s. What is the instantaneou
pochemuha

Answer: Rate of decomposition of acetaldehyde in a solution is 1.45\times 10^{-14}mol/Ls

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

For a reaction : A\rightarrow products

Rate=k[A]^x

k= rate constant

x = order of the reaction = 2

Rate=4.71\times 10^{-8}L/mol/s\times {5.55\times 10^{-4}M}^2

Rate=1.45\times 10^{-14}

Thus rate of decomposition of acetaldehyde in a solution is 1.45\times 10^{-14}mol/Ls

slava [35]
We can use a ratio to solve this question. Lets refer to the amount formed by the formula as a serving
1 serving needs 3/8 gal
We want to create 7/9 servings extra, so
1 + 7/9 = 16/7
1 : 3/8
16/7 : x
1/(3/8) = (16/7) / x
8 / 3 = 16x / 7
x = 7/6
He needs to use 7/6 gallons of water.
