That's why it's important for you to use water wisely and not to waste it. When you waste water, you're taking water that other people might need. But when you use water carefully, you leave more water for other people to use. It is also important to use water carefully because our weather can be unpredictable.

Mass of HCl=1190g soln ×37.7g HCl100g soln =448.6 g HCl.Calculate the moles of HCl . ...Calculate the molarity of the HCl.</span>
<h3>
Answer:</h3>
500 Joules
<h3>
Explanation:</h3>
<u>We are given;</u>
- Force is 100 N
- Distance is 5 m
We are required to calculate the work done;
- Work done is the product of force and distance.
- That is, work done = Force × distance
- Work is measured in Joules
Thus, in this case;
Work done = 100 N × 5 m
= 500 Joules
Thus, the work done in moving the box is 500 joules
