Answer:
0.301 m
Explanation:
Torque = Force × Radius
τ = Fr
40.0 Nm = 133 N × r
r = 0.301 m
The mechanic must apply the force 0.301 m from the nut.
<h2>Hello!</h2>
The answer is: There are 3.42 moles of MgCl2 in 326g of the compound.
<h2>Why?</h2>
Assuming that the compound is MgCl2, we can find how many moles of the compound are in 326 g of the same compound, calculating the molar mass of the compound, so:

Then,

Therefore, to calculate how many moles are in 326 of the compound, we can use the following equation

Hence,
There are 3.42 moles of MgCl2 in 326g of the compound.
Have a nice day!
