If you had 1.00 kg of each kind of hardware, how many boxes of each would you<br> have?
dusya [7]

The number of boxes is calculated by dividing the

total mass of hardware boxes by 1.00 kg

<h3>What is a hardware?</h3>

A hardware is a physical component of a system that can be touched and felt.

Because hardware are physical components, they always have a given mass.

Assuming, several hardware each of mass 1.00 kg is available to be chosen from.

Also, assuming that the sum total of the mass of all the hardware is known.

The number of boxes can be calculated as follows:

  • total mass of hardware/1.00 kg

Therefore, the number of boxes is obtained by dividing the sum of the mass of the boxes by 1.00 kg.

Methanol (CH3OH) is produced commercially by the catalyzed reaction of carbon monoxide and hydrogen:
Effectus [21]

Answer: Kc= 4.653

Explanation:

From The equation of reaction

CO(g)+2H2(g)⇌CH3OH(g)

From the question

[CH3OH] =0.0679 moles

[CO]= 0.160moles

[H2]= 0.302

Kc = [CH3OH]/[CO] [H2]^2

Kc=[0.069]/[0.16]×[0.302]^2

Kc= 4.653
