You are measuring an Intensive property
<u>Answer:</u>
5
<u>Explanation:</u>
We know that,
number of count of cardinals = 75; and
measured area = 15 square kilometers.
To find the population density of the cardinals in an area of 15 square kilometers, we need to divide the number of cardinals by the given unit area:
Population density of cardinals = 75 / 15 = 5
Therefore, the population density of cardinals in an area measuring 15 square kilometers is 5.
The volume of 6.00g iron is 0.762 cm^3.
<em>Step 1</em>. Calculate the <em>density of Fe</em>
The <em>specific gravity</em> (SG) of a substance is the ratio of its density to the density of water at 4 °C.
SG = density of substance/density of water.
∴ 7.87 = density of iron/1.00 g·cm^(-3)
Density of Fe = 7.87 × 1.00 g·cm^(-3) = 7.87 g·cm^(-3)
<em>Step 2</em>. Calculate the <em>mass of Fe</em>
Volume of Fe = 6.00 g Fe × (1 cm^3 Fe/7.87 g Fe) = <em>0.762 cm^3</em>
