Look at the image and calculate the mass.

The image shows a triple beam balance, which is an instrument for measuring mass

The mass in the image is 290.2 grams

The reason for arriving at the above answer is as follows;

The triple beam balance is a measuring instrument used for making

precise mass measurement to an accuracy of ±0.05 grams. The three

beams it consists of is what is referred to in its name

To measure a mass using the triple beam balance, after adjusting the

sliders to have an balance point as seen on the pointer balance, the

number representing the positions of the three sliding masses on the three

beams are added to give the mass

In the given image, we have;

The position of the 10-gram slider = 90-grams

The position of the 100-gram slider = 200-grams

The position of the 1-gram slider = 0.2-grams

The mass reading is therefore;

Mass = 90 g + 200 g + 0.2 g = 290.2 g

The mass is 290.2 grams
