Answer: 6.65 bullfrogs per square
kilometer
Explanation:
The formula to calculate the population density will be:
= N/A
where,
N = total population = 452
A = land area = 68km²
Therefore, population density will be:
= N/A
= 452/68
= 6.65 bullfrogs per square
kilometer
Density = mass / Volume 0.856 g/cm3 = x / 30 cm3(0.856)(30) = xx = 25.68 grams
The particles can move around each other because they do not have as strong bonds as solids do.
