Answer:

The K_{m} of a substrate will be "10 μM".

Explanation:

The given values are:

E_{t} = 20 \ nM

[Substract] = 40 \ \mu M

K_{cat}=600 \ s^{-1}

Reaction velocity, Vo=9.6 \ \mu M s^{-1}

As we know,

⇒  Vo=\frac{K_{cat}[E_{t}][S]}{K_{m}+[S]}

On putting the estimated values, we get

⇒  9.6=\frac{600\times 20\times 10^{-3}\times 40}{K_{m}+40}

⇒  K_{m}+40=\frac{600\times 20\times 10^{-3}\times 40}{9.6}

⇒  K_{m}+40=50

On subtracting "40" from both sides, we get

⇒  K_{m}+40-40=50-40

⇒  K_{m}=10 \ \mu M

A hardware salesman measures the mass of a box containing
sattari [20]

Step 1

<u>find the mass of a single washer</u>

Divide the total mass by the number of washers

\frac{0.4168}{1000} =0.0004168\ Kg

0.0004168kg=4.168*10^{-4} kg

Step 2

<u>Convert kg to mg</u>

we know that

1 kg=1*10^{6} mg

so

4.168*10^{-4}*10^{6} =4.168*10^{2}mg=416.8 mg

therefore

<u>the answer is</u>

416.8 mg
