Question

1. a block of lead has dimensions of 4.50 cm by 5.20 cm by 6.00 cm. the block has a mass of 1587 g. from this information, calculate the density of lead. (d = m/v)

Explanation:

Step1: Calculate the volume of the block

The volume $V$ of a rectangular - block is given by $V = l\times w\times h$, where $l = 4.50\ cm$, $w = 5.20\ cm$, and $h = 6.00\ cm$.
$V=4.50\times5.20\times6.00 = 140.4\ cm^{3}$

Step2: Calculate the density

The density formula is $D=\frac{M}{V}$, where $M = 1587\ g$ and $V = 140.4\ cm^{3}$.
$D=\frac{1587}{140.4}=11.3\ g/cm^{3}$

Answer:

$11.3\ g/cm^{3}$
