While molar mass is typically written in grams per mole, is the ratio moles per gram also acceptable?

1 answer:

6 0

Answer is: y<span>es, because the ratios of grams and moles would be similiar.

For example, molecule of water:
1) M(H</span>₂O) = 2Ar(H) + Ar(O) · g/mol.
M(H₂O) = 2 + 16 · g/mol.
M(H₂O) = 18 g/mol; molar mass of water
Ratio grams and moles is 18 : 1.
2) if we write molar mass as ratio mole and grams (1 mol/18 g), ratio is of grams and moles is still the same 18 : 1.

When the temperature of a sample of pure water is raised above 25 °C,(1)the hydronium ion concentration will be greater than the

Ludmilka [50]

Answer:

The correct answer is option 3.

Explanation:

$H_2O\rightleftharpoons H^++OH^-$

The expression of $K_w$ is given by :

$K_w=[H^+][OH^-]$

$K_w\propto [H^+]$

$K_w\propto [OH^-]$

Rise in temperature will result in more dissociation of water molecules into hydrogen ions and hydroxide ions.

With an increase in concentration of hydrogen ions and hydroxide ions value of $K_w$ will also increase.

Which of the following statement(s) is/are TRUE for the citric acid titration?

RoseWind [281]

Under-titrating means too little indicator was added to the reaction.

TRUE

Since the volume of titrant is too small, multiplying by a small number in the calculation of citric acid makes the mass of citric acid too low.

TRUE

The reaction was stopped too quickly (before reaction was complete).

FALSE

How are cellular respiration and photosynthesis similar

Nimfa-mama [501]

<h2>Answer:</h2><h2><em>Cellular respiration takes a glucose molecule and combines it with oxygen; the result is energy in the form of ATP, along with carbon dioxide and water as waste products. Photosynthesis takes carbon dioxide and combines it with water, enabled by radiant energy, usually from the sun.</em></h2><h2><em>Explanation:</em></h2><h2><em></em></h2>
