Just use the formula you gave, we have 15 newtons and 2.0 meters, therefore you torque is 30 N*m
Most of these look like dilution questions which follow a general pattern;
<span>Use M1V1 = M2V2 (because moles in a solution stays constant if diluted) </span>
<span>so, the Concentration before * Volume before = Concentration after * Volume after </span>
<span>Using the first question as an example; 0.2*50 = 100 * M2 </span>
<span>Rearranging for M2: 0.1 </span>
<span>Therefore the concentration of the final solution is 0.1 M </span>
<span>we know that to work out pH you must use negative logs to base 10; i.e. -log(0.1) gives you the pH for this solution which is 1</span>
