Answer:

5.22*1022 molecules of glucose (C6H12O6) is equal to 15.08 grams

Explanation:

Number of molecule of glucose in one mole $= 6.023 * 10^{23}$

Now mass of one mole of glucose $= 180$ grams

Number of moles in $6.023 * 10^{23}$ molecules of glucose $= 1$

Number of moles in $1$ molecules of glucose = $\frac{1}{6.023 * 10^{23}}$

Number of moles in $5.22 * 10^{22}$ molecules of glucose = $\frac{5.22* 10^{22}}{6.023 * 10^{23}}$ = $0.083$ moles

Weight of $0.083$ moles

$= 0.083 * 180\\= 15.08$ grams

A 250mL sample of oxygen is collected over water at 30 C and 850 torr pressure. What is the pressure of the dry gas alone?

3241004551 [841]

Answer:

$p_O=818.2torr$

Explanation:

Hello there!

In this case, according to the given equation, it is possible to calculate the mass of oxygen by using the Dalton's law, considering that the total pressure is 850 torr and the vapor pressure of water at 30°C is 31.8 torr:

$P_T=p_O+p_{H_2O}$

Thus, we solve for the pressure of oxygen as follows:

$p_O=P_T-p_{H_2O}\\\\p_O=850torr-31.8torr\\\\p_O=818.2torr$

Best regards!

In the reaction of silver nitrate with sodium chloride, how many grams of silver chloride will be produced from 100. g of silver

pantera1 [17]

Answer:

The mass in grams of silver chloride, AgCl produced is 84.37 grams

Explanation:

The chemical equation for the reaction is given as follows;

AgNO₃ + NaCl → AgCl + NaNO₃

The mass of silver nitrate, AgNO₃, in the reaction = 100.0 g

Therefore, 1 Mole of AgNO₃ produces 1 mole of AgCl,

The molar mass of silver nitrate, AgNO₃ = 169.87 g/mol

The number of moles of silver nitrate, AgNO₃, in the reaction = 100/169.87 moles

The number of moles of silver nitrate, AgNO₃, in the reaction ≈ 0.59 moles

Since 1 mole of AgNO₃ produces 1 mole of AgCl, 0.59 moles of AgNO₃ produces 0.59 moles of AgCl

The number of moles of silver chloride, AgCl produced = 0.59 moles

The molar mass of silver chloride, AgCl = 143.32 g/mol

Therefore;

The mass of silver chloride, AgCl produced = The number of moles of silver chloride, AgCl produced × The molar mass of silver chloride, AgCl

Which gives;

The mass of silver chloride, AgCl produced = 143.32 g/mol × 0.59 moles = 84.37 g

The mass of silver chloride, AgCl produced = 84.37 g.

Which is a function of the gallbladder

Alinara [238K]

Answer:

<h3>Gall Bladder:</h3>

The gallbladder is a pear-shaped, hollow structure located under the liver and on the right side of the abdomen. Its primary function is to store and concentrate bile, a yellow-brown digestive enzyme produced by the liver.

Without a gallbladder, there's no place for bile to collect. Instead, your liver releases bile straight into the small intestine. This allows you to still digest most foods. However, large amounts of fatty, greasy, or high-fiber food become harder to digest.

The gallbladder is part of the biliary tract. The gallbladder serves as a reservoir for bile while it's not being used for digestion. The gallbladder's absorbent lining concentrates the stored bile.

Which of the following occurs when a covalent bond forms? Which of the following occurs when a covalent bond forms? Partial char

Alexus [3.1K]

Answer: Option (b) is the correct answer.

Explanation:

A covalent bond is defined as the bond which occurs due to sharing of electrons between the combining atoms.

Generally, a covalent bond is formed between non-metals.

For example, both nitrogen and oxygen atoms are non-metals and they combine covalently to form $NO_{2}$ compound.

As nitrogen has 5 valence electrons and an oxygen atom has 6 valence electrons. So, there occurs unequal sharing of electrons between the two.

Thus, we can conclude that when a covalent bond forms then electrons in valence shells are shared between atoms.
