To calculate the volume and density of an ore sample weighing 15.00 N in air, we can follow these steps:
### Step 1: Calculate the Mass
First, we need to convert the weight of the ore sample from Newtons (N) to mass (kilograms) using the equation:
\[
\text{Weight} = \text{mass} \times g
\]
where \( g \) (acceleration due to gravity) is approximately \( 9.81 \, \text{m/s}^2 \).
Rearranging the equation gives us:
\[
\text{mass} = \frac{\text{Weight}}{g}
\]
Plugging in the values:
\[
\text{mass} = \frac{15.00 \, \text{N}}{9.81 \, \text{m/s}^2} \approx 1.53 \, \text{kg}
\]
### Step 2: Calculate the Volume
To find the volume of the ore sample, you would typically need to know the density of the ore or perform a measurement using a method such as water displacement. However, if you do not have any additional information about the density, we cannot directly calculate the volume. Assuming you have the density \( \rho \) in kilograms per cubic meter (kg/m³), you can use the formula:
\[
\text{Volume} = \frac{\text{mass}}{\text{density}}
\]
If you have a known or measured density for the ore, plug in the mass you calculated and the density to find the volume.
### Step 3: Calculate the Density
If you have measured the volume of the sample (let's call it \( V \) in m³), you can calculate the density using the formula:
\[
\text{Density} = \frac{\text{mass}}{\text{Volume}}
\]
### Summary
1. The mass of the ore sample is approximately \( 1.53 \, \text{kg} \).
2. To calculate volume, you need the density. If density is available, use \( \text{Volume} = \frac{\text{mass}}{\text{density}} \).
3. To find density if you have the volume, use \( \text{Density} = \frac{\text{mass}}{\text{Volume}} \).
Please provide the density or the volume if you have them for more specific calculations.
