Figure 1 shows a balanced laboratory scale beam resting on a central pivot, used to compare the weights of two chemical sample containers.

Laboratory scale beam with Container X and Container Y

Calculate the value of WWW, the weight of Container Y.

Use the principle of moments and the equation:

the moment of W=the moment of the weight of Container X \text{the moment of } W = \text{the moment of the weight of Container X} the moment of W=the moment of the weight of Container X

Give your answer to 2 significant figures.
