Wet chemical system components typically are a storage tank or tanks, piping, nozzles, and a(an)?
MAVERICK [17]

Wet chemical system components typically are a storage tank or tanks, piping, nozzles, and an actuating mechanism.

<h3>Which parts make up an actuation mechanism?</h3>

The typical components of an actuation mechanism include a motor, transmission, control units, feedback, signaling, interlocking, and shutdown units. An electrical, hydraulic, or pneumatic drive is used to move a valve, shutter, or gate, which acts as an actuator to regulate the flow of fluids or gases.

<h3>What is the operation of the operator-dependent actuating mechanism?</h3>

When an automatic clutch is engaged, the control system 2 replaces the target-value signals coming over feeders 1 with the operator force signal if the operator uses the operator-dependent actuating mechanism.

What is the mass of KOH found in a 785 mL of a 1.43 M solution of KOH
My name is Ann [436]

Molarity is defined as the ratio of number of moles to the volume of solution in litres.

The mathematical expression is given as:

Molarity = \frac{Number of moles}{volume of solution in litres}

Here, molarity is equal to 1.43 M and volume is equal to 785 mL.

Convert mL into L

As, 1 mL = 0.001 L

Thus, volume = 785\times 0.001 = 0.785 L

Rearrange the formula of molarity in terms of number of moles:

Number of moles =molarity\times volume of solution in litres

n = 1.43 M \times 0.785 L

= 1.12255 mole

Now,  Number of moles  = \frac{mass in g}{molar mass}

Molar mass of potassium hydroxide  = 56.10 g/mol

1.12255 mole  = \frac{mass in g}{56.10 g/mol}

mass in g = 1.12255 mole\times 56.10 g/mol

= 62.97 g

Hence, mass of KOH = 62.97 g
