Question

Determine the most suitable material using TOPSIS method for which attribute data is as shown in Table. Assume weights as 0.32, 0.28 and 0.40 for hardness, machinability rating and cost respectively.

Answer 1

Determine the most suitable material using TOPSIS method for which attribute data is as shown in Table. Assume weights as 0.32, 0.28 and 0.40 for hardness, machinability rating and cost respectively.

Answer 2

Explanation:

Given mass of CO2 = 52Grams

Molar mass of CO2 = 44 Gram

where:-

Mass of Carbon =12g

mass of oxygen =16 g

Moles of CO^2

= 44/4.4

=0.1

Volume of 1 mole = 22.4 L

Volume of 0.1 mole = 2.24 L
