Question

a piece of lead has a volume 50cm3 and density 11.5gcm-3 find the mass of piece of lead​

Answer 1

Answer:

plz mark me as brainly

mass of the piece of the lead   =d into v

                                                  = 11.5gcm-3 into 50cm

575

Answer 2

Answer:

The mass of a piece of lead will be equal to 575g.

Explanation:

Given: The piece of lead occupies the volume, $V=50cm^{3}$

The density of the lead piece $d=11.5gcm^{-3}$

We can define the density as mass per unit volume.

Write the formula of density that we can use to find mass:

Density = (mass)/ (Volume)                      

Then, mass = (density)×(volume)

⇒   $m=d*V$                                                            ...................(1)

Put the value of V= 50cm³ and d=7.8gcm⁻³ in eq.(1),

⇒   $m=(11.5gcm^{-3})(50cm^{3})$

∴    $m=575g$

Therefore, the mass of lead piece will be equal to 575g.
