The balance that can be used to measure a mass reading of 6.521 g will be a balance with ±0.001 g tolerance.
<h3>What is the tolerance of a balance?</h3>
The tolerance of a balance is the number of decimal place values displayed on the balance and it is the acceptable measurement limitations (in grams) that a balance can tolerate.
- As such, depending on the decimal place value behind a mass reading will determine the balance used for measurement.
Since no mass reading was given, let's make two assumptions about mass reading.
Mass reading Assumptions
1 6.521 g
2 4.23 g
- The balance used for the 6.521 g mass reading is a balance with ±0.001 g tolerance.
- The balance used for the 4.23 g mass reading is a balance with ±0.01 g tolerance.

<span>In a centrally planned economy, the government owns and operates production facilities and manages the flow of supply and demand rather than allowing interactions between businesses and consumers to determine supply and demand.
In a pure market economy the government has no role. Instead, the market makes all allocation decisions.
In a market economy, the government does not oversee the day to day micro transactions. Instead, it oversees the economy, making sure that it steps in to stabilize the market if it is going through a recession. The government is also allowed to step in and prevent trade or business with any country that it feels is a threat.
