Answer:

201.6 grams is the mass of 6.3 moles of sulfur.

Explanation:

Moles(n) =\frac{\text{Mass of the compound}(m)}{\text{molar mass of the compound}(M)}

Moles of sulfur ,n= 6.3 moles

Atomic mass of sulfur = M = 32 g/mol

Mass of the sulfur = m = ?

m=M\times n

=6.3 mol\times 32 g/mol=201.6 g

201.6 grams is the mass of 6.3 moles of sulfur.

Calculate the Experimental Molar Volume in L/mol of the Hydrogen gas, H2, if the volume of H2 at STP is 52.8 mL and the mass of
lana66690 [7]

Answer:

The Experimental Molar Volume in L/mol of the Hydrogen gas=23.36L/mol

Explanation:

We are given that

Volume of H2 at STP=52.8mL

Mass of magnesium metal ,M(Mg)=0.055g

We have to find the Experimental Molar Volume in L/mol of the Hydrogen gas.

Molar mass of Mg=24.305 g/mol

Number of moles=\frac{given\;mass}{molar\;mass}

Using the formula

Number of moles of Mg=\frac{0.055}{24.305}moles

Number of moles of Mg=0.00226moles

Number of moles of Mg=Number of moles of H2

Number of moles of H2=0.00226moles

Molar volume of Hydrogen gas (H2)=\frac{volume\;at\;STP}{No\;of\;moles\;H_2}

Molar volume of Hydrogen gas (H2)=\frac{52.8}{0.00226}mL/mol

Molar volume of Hydrogen gas (H2)=\frac{52.8}{0.00226}\times 10^{-3}L/mol

1L=1000mL

Molar volume of Hydrogen gas (H2)=23.36L/mol

Hence, the Experimental Molar Volume in L/mol of the Hydrogen gas=23.36L/mol

a. The circulatory system in fish is one-directional while it is two-directional in humans.

b. P has a high concentration of carbon dioxide and low oxygen concentration whereas Q has high oxygen concentration and low carbon dioxide concentration.

<h3>What is the circulatory system?</h3>

The circulatory system is the system of organism and tissues which help to transport blood and other fluids through the body of a living organism.

The organs of the circulatory system include:

  • The heart
  • The blood vessels - veins, arteries, capillaries

a. In the given diagram sowing the circulatory system of man and the fish, it can be seen that the direction of blood flow in the fish is one way through the heart. However, in humans, the direction of blood flow is two-way through the heart.

b. The gas in P has a high concentration of carbon dioxide and low oxygen concentration. However, the gas flowing through Q has high oxygen concentration and low carbon dioxide concentration.

In conclusion, the circulatory system is important in the exchange of gases in the body.
