Record the mass of the object based on the reading from the triple-beam balance. The mass of the object is ____ grams.

Answers

Hello!

[tex]\large\boxed{167g}[/tex]

Looking at the balance, we see that:

The middle beam reads 100g.

The top beam reads 60g.

The bottom beam reads 7g.

Add all of the numbers together to get the total mass:

100 + 60 + 7 = 167g.

The mass of the object is 167 grams.

Explanation:

A triple beam balance is a mass measuring instrument used in labs to measure the mass of a substance. It unit in which it measures is grams. It consists of three beams which are: The middle beam has  Increments of 100 grams  The front beam has  Increments from 0 grams  to 10 grams  The farther beam has  Increments of 10 grams

Given :

Readings of all the scales of three beams of the triple beam balance of an object.

To find :

The mass of object whose reading on triple beam balance is given.

Solution:

Middle beam reader at 100 grams

Front beam reader at 7 grams

Farther beam reader at 60 grams

The mass of object:

[tex]100 grams + 7 garms + 60 grams = 167 grams[/tex]

The mass of the object is 167 grams.
