Answer:

A research was interested in whether there was a difference in appearance management by

gender and the situation context. For example, on a romantic date, group date or out with

friends. Using the data provided determine whether there are statistically significant

differences in appearance management (measured in seconds) by gender and situational

context. Include all four hypothesis testing steps and α = .05 level of significance.

N = 36

n = 6

K = 6

G = 258

∑x2 = 2406

SSW = 204

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
