The actual density of iron is 7.874 g/mL. In a laboratory investigation, Jason finds the density of a piece of iron to be 7.921
mixas84 [53]

The percent error associated with Jason’s measurement is 0.596%.

HOW TO CALCULATE PERCENTAGE ERROR:

  • The percentage error of a measurement can be calculated by following the following process:
  1. Find the difference between the true value and the measured value of a quantity.
  2. Then, divide by the true value and then multiplied by 100

  • The true value of the density of iron is 7.874 g/mL
  • Jason observed value is 7.921 g/mL

Difference = 7.921 g/mL - 7.874 g/mL

Difference = 0.047 g/mL

Percentage error = 0.047/7.874 × 100

Percentage error = 0.596%.

Therefore, the percent error associated with Jason’s measurement is 0.596%.

A lead atom has a mass of 3.14 x 10 to the negative 22nd g.How
frozen [14]

Explanation:

The given data is as follows.

       Mass of a lead atom = 3.14 \times 10^{-22}

       Volume = 2.00 cm^{3}

        Density = 11.3 g/cm^{3}

As it is mentioned that 1 cubic centimeter contains 11.3 grams of lead.

So, in 2 cubic centimeter there will be 2 \times 11.3 g = 22.6 g of lead atoms.

One lead atom has a mass of 3.14 \times 10^{-22}. Therefore, number of atoms present in 22.6 g of lead will be as follows.

                \frac{22.6 g}{3.14 \times 10^{-22}}

                  = 7.197 \times 10^{22} atoms

Thus, we can conclude that there are 7.197 \times 10^{22} atoms of lead are present.
