Chemistry
1 answer:
Thepotemich [5.8K]3 years ago
8 0

Answer:

Mass = 110.88 g

Explanation:

Given data:

Mass of CO₂ = ?

Number of moles of CO₂ = 2.52 mol

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of CO₂  = 44 g/mol

by  putting values,

Mass = 2.52 mol × 44 g/mol

Mass = 110.88 g

(a) what is the approximate ductility (%el) of a brass that has a yield strength of 230 mpa (33360 psi)?
ss7ja [257]

Based on the calculations, the approximate ductility (%el) of this brass is equal to 2.3%.

<u>Given the following data:</u>

  • Yield strength = 230 mpa (33360 psi).

<h3>What is ductility?</h3>

Ductility can be defined as an important property of a material which determines its ability to become elongated due to the application of stress.

Mathematically, the ductility of a material can be expressed as percentage elongation in length:

\% el = \frac{\Delta L}{L_i} =\frac{L_f - L_i}{L_i}

<u>Where:</u>

  • L_i is the original length.
  • L_f is the final length.
  • \Delta L is the yield strength.

For this exercise, let us assume the original length of this brass is equal to 100 meters.

Substituting the parameters into the formula, we have;

\% el = \frac{230}{100}

Ductility = 2.3%.
