Question

If a nickel has a mass of 5 grams and a volume of approx 0.689cm^3 what is the density

Answer 1

Density is a mathematical expression that calculates the mass of the object by its volume:

Data:
m (mass) = 5 grams
v (volume) ≈ 0.689 cm³
d (density) = ?

Formula:
$d = \frac{m}{v}$

Solving:
$d = \frac{m}{v}$
$d = \frac{5}{0.689}$
$\boxed{\boxed{d \approx 7.25\:g/cm^3}}\end{array}}\qquad\quad\checkmark$
