Answer: The density of lead will be 
Explanation:
Density is defined as the mass contained per unit volume.

Given : Mass of lead=
Volume of lead =
Putting in the values we get:

Thus density of lead will be 
Constant:
Test tubes
Independent:
<span>volume of gas
Dependent:
</span>
<span>amount of H2O2 </span>
Answer:

Explanation:
Hello,
In this case, considering that the density is considered as the quotient of the mass and volume:

We can easily compute the mass by solving for it as follows:
