Which excerpt from "the enigma machine" supports the claim that german soldiers accidentally helped the allies figure out the en

igma codes? with the right settings, the recipient only needed to type in the encrypted text and the message would light up in plain text. To use the enigma machine, an operator typed a message into the machine, which would be scrambled by three rotors. . . The polish intelligence developed the "bomba", a complicated system of wires and rotors to scan and decode messages within hours. Typing in messages was a boring task, so operators took shortcuts, like choosing three letters in a row or other simple, predictable patterns.

If there are 12 x 1023 oxygens in a sample of water, how many grams of hydrogen are in the sample?.
AveGali [126]

The amount of grams of hydrogen that are in the water sample is;

3.985 g

<h3>Avogadro's number</h3>

We are given that;

Number of moles of oxygen in a sample of water = 12 × 10²³

  • Now, the chemical formula of a molecule of water is H₂O. This means that for every 1 atom or molecule of oxygen, there must be 2 hydrogen atoms or molecules present.

Since Number of moles of oxygen in the sample is 12 × 10²³, then number of moles of hydrogen will be twice that = 2 × 12 × 10²³ = 24 × 10²³ moles

Now, molar mass of hydrogen is 1 g/mol and we know that;

Molar mass = Avogadro's number(6.023 × 10²³) moles

Thus;

6.023 × 10²³ moles = 1 g/mol

Thus; 24 × 10²³ moles of hydrogen = ( 24 × 10²³ × 1)/(6.023 × 10²³)

⇒ 3.985 g
