Question

A balance measures mass to $0.001\mathrm{g}$. If you determine the mass of an object that weighs about $31\mathrm{g}$, would you record the mass as $31g,31.1g,31.0Sg,31.075g,or31.0750$ ? Explain your choice by writing two to three complete sentences that describe your thinking. (2.3)

Short answer

The record mass of an object is determined as$31.075g$

Step-by-step solution

Given Information 

The given is the mass measured by a balance.

The objective is to explain the choice and describe the thinking.

The recorded information are : $531\mathrm{g},31.1\mathrm{g},31.0\mathrm{s}g,31.075\mathrm{g},\text{or}31.0750$

Explanation 

After the decimal point, the balance measures mass up to three digits.

As a result, after the decimal point, you would record the mass up to three digits.

As a result, the record mass of an object from balance is $31.075g$
