The density of lead (Pb) is 11.34 g/cm3. If I have 2.6 cm3, what mass of lead do I have?

The answer is

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

volume of lead = 2.6 cm³

density of lead = 11.34 g/cm³

The mass of lead is

mass = 11.34 × 2.6 = 29.484

We have the final answer as

Hope this helps you

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
