<h3>Answer:</h3>

0.211 moles

<h3>Explanation:</h3>

From the Question;

Molecules of H₂O = 1.27 × 10^23 molecules

We are required to calculate the number of moles

we need to know that 1 mole of a compound contains a number of molecules equivalent to the Avogadro's constant, 6.022×10^23.

Therefore, 1 mole of water, H₂O = 6.022×10^23 Molecules

To get the number of moles we divide number of molecules by the Avogadro's number.

Number of moles of water = 1.27 × 10^23 molecules ÷ 6.022 × 10^23 molecules

= 0.211 Moles

Thus, the number of moles of water that are equal to 1.27 × 10^23 molecules is 0.211 moles.

Which substance has a mass is 13.5 grams, and its volume is 5 cm 3.

solmaris [256]

Answer:

Substance is Aluminium

Explanation:

We are given;

Mass; m = 13.5 grams

Volume; V = 5 cm³

Formula for density is;

density = m/V

Density = 13.5/5

Density = 2.7 g/cm³

From the table attached, we can see that the element with a corresponding density of 2.7 is Aluminium

What are the concentrations of h3o+ and oh− in tomatoes that have a ph of 4.10?

IRINA_888 [86]

Answer : The concentration of $H_3O^+$ and $OH^-$ are $7.94\times 10^{-5}$ and $1.258\times 10^{-10}$ respectively.

Solution : Given,

pH = 4.10

pH : pH is defined as the negative logarithm of hydronium ion concentration.

Formula used : $pH=-log[H_3O^+]$

First we have to calculate the hydronium ion concentration by using pH formula.

$4.10=-log[H_3O^+]$

$[H_3O^+]=antilog(-4.10)$

$[H_3O^+]=7.94\times 10^{-5}$

Now we have to calculate the pOH.

As we know, $pH+pOH=14$

$4.10+pOH=14$

$pOH=9.9$

Now we have to calculate the hydroxide ion concentration.

$pOH=-log[OH^-]$

$9.9=-log[OH^-]$

$[OH^-]=antilog(-9.9)$

$[OH^-]=1.258\times 10^{-10}$

Therefore, the concentration of $H_3O^+$ and $OH^-$ are $7.94\times 10^{-5}$ and $1.258\times 10^{-10}$ respectively.

Natalija [7]

Answer:

The energy of electromagnetic radiation increases as its frequency increases.

The frequency and wavelength of electromagnetic radiation are inversely proportional.

Explanation:

According to Max Plank's equation, the energy of electromagnetic radiation is given by E=hf where h= Plank's constant and f= frequency of the electromagnetic radiation. This means that the energy and frequency of electromagnetic radiation and its energy are related by a direct proportion. As frequency of the electromagnetic radiation increases, the energy of the radiation increases also.

However, frequency and wavelength of electromagnetic radiation are inversely related. The frequency decreases with increasing wavelength of electromagnetic radiation.
