Calculating the Ratio for All Six Pairs of Values

Oct 13, 2025 by sorusgentrification.com 107 views

In chemistry, the relationship between volume and temperature is a crucial concept that helps us understand the behavior of gases. The ideal gas law, which is a fundamental principle in chemistry, states that the volume of a gas is directly proportional to the temperature. Mathematically, this can be expressed as:

${ PV = nRT }$

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.

However, in this article, we will focus on the relationship between volume and temperature, which can be expressed as:

${ \frac{V}{T} = \frac{0.72}{276} = 0.0026 }$

This equation represents the ratio of the volume divided by the temperature for the first data pair.

Calculating the Ratio for All Six Pairs of Values

To calculate the ratio for all six pairs of values, we will use the same equation:

${ \frac{V}{T} = \frac{V}{T} }$

We will substitute the values of V and T for each pair of values and calculate the ratio.

Pair 1: V = 0.72, T = 276

${ \frac{V}{T} = \frac{0.72}{276} = 0.0026 }$

Pair 2: V = 0.75, T = 280

${ \frac{V}{T} = \frac{0.75}{280} = 0.0027 }$

Pair 3: V = 0.78, T = 284

${ \frac{V}{T} = \frac{0.78}{284} = 0.0028 }$

Pair 4: V = 0.81, T = 288

${ \frac{V}{T} = \frac{0.81}{288} = 0.0028 }$

Pair 5: V = 0.84, T = 292

${ \frac{V}{T} = \frac{0.84}{292} = 0.0029 }$

Pair 6: V = 0.87, T = 296

${ \frac{V}{T} = \frac{0.87}{296} = 0.0030 }$

Calculating the Average of All Six Ratios

To calculate the average of all six ratios, we will add up all the ratios and divide by 6.

${ \text{Average} = \frac{0.0026 + 0.0027 + 0.0028 + 0.0028 + 0.0029 + 0.0030}{6} }$

${ \text{Average} = \frac{0.0168}{6} }$

${ \text{Average} = 0.0028 }$

Therefore, the average of all six ratios is 0.0028.

Significant Figures

When performing calculations, it is essential to consider significant figures. Significant figures are the digits in a measurement that are known to be reliable and certain. In this case, we will use the following rules to determine the number of significant figures:

Non-zero digits are always significant.
Zeros between non-zero digits are significant.
Zeros at the end of a number are not significant unless the number contains a decimal point.
Zeros at the beginning of a number are not significant.

Using these rules, we can determine the number of significant figures for each ratio.

Pair 1: V = 0.72, T = 276

${ \frac{V}{T} = \frac{0.72}{276} = 0.0026 }$

The number 0.72 has 3 significant figures.
The number 276 has 3 significant figures.
The ratio 0.0026 has 3 significant figures.

Pair 2: V = 0.75, T = 280

${ \frac{V}{T} = \frac{0.75}{280} = 0.0027 }$

The number 0.75 has 3 significant figures.
The number 280 has 3 significant figures.
The ratio 0.0027 has 3 significant figures.

Pair 3: V = 0.78, T = 284

${ \frac{V}{T} = \frac{0.78}{284} = 0.0028 }$

The number 0.78 has 3 significant figures.
The number 284 has 3 significant figures.
The ratio 0.0028 has 3 significant figures.

Pair 4: V = 0.81, T = 288

${ \frac{V}{T} = \frac{0.81}{288} = 0.0028 }$

The number 0.81 has 3 significant figures.
The number 288 has 3 significant figures.
The ratio 0.0028 has 3 significant figures.

Pair 5: V = 0.84, T = 292

${ \frac{V}{T} = \frac{0.84}{292} = 0.0029 }$

The number 0.84 has 3 significant figures.
The number 292 has 3 significant figures.
The ratio 0.0029 has 3 significant figures.

Pair 6: V = 0.87, T = 296

${ \frac{V}{T} = \frac{0.87}{296} = 0.0030 }$

The number 0.87 has 3 significant figures.
The number 296 has 3 significant figures.
The ratio 0.0030 has 3 significant figures.

Therefore, the number of significant figures for each ratio is 3.
