80.0 grams of NaOH is dissolved in water to make a 6.00 L
solution. What is the molarity of the solution? (Molar mass of NaOH
= 40.0 g/mol)
M М.

Answers

Answer:

0.333 M

Explanation:

Divide the mass of NaOH by the molar mass and then divide by the volume.

80.0 g / 40.0 g/mol = 2.00 mol NaOH

2.00 mol NaOH / 6.00 L = 0.333 M NaOH

A greenhouse is filled with air that cotains more carbon dixoide than normal air has. How might phothsyphness and plant growth be affeacted

Answers

Answer:

See explanation

Explanation:

We know that photosynthesis involves the combination of carbon dioxide and water in the presence of sunlight to yield glucose.

If the atmosphere is rich in carbon dioxide such as in a green house where air is filled with carbon dioxide, the rate of photosynthesis is increased.

As the rate of photosynthesis is increased, the growth of plants is also increased.

Hence, in a greenhouse where the air contains more carbon dioxide, the rate of plant growth increases.

A 2.50 L sample of butane gas (C4H10), measured at 22.0
oC and 1.20 atm pressure, is combusted completely and
the carbon dioxide gas collected at the same pressure and
temperature. What volume of CO2 is produced?

Answers

Answer:

Same i guess hdjekfhkshfjfkr

The resultant volume of the carbon dioxide gas which is produced by the combustion of butane is 14.4L.

How do we calculate the moles of gas?

Moles of any gas will be calculated by using the ideal gas equation as:

PV = nRT, where according to qustion for butane gas

P = pressure = 1.20 atm

V = volume = 2.50L

n = moles = ?

R = universal gas constant = 0.082 L.atm / K.mol

T = temperature = 22 degree celsius = 295.15 K

On putting values we get

n = (1.20)(2.50) / (0.082)(295.15) = 0.124 moles

Given chemical equation is:

C₄H₁₀ + 13/2O₂ → 4CO₂ + 5H₂O

From the stoichiometry of the reaction, it is clear that,

1 mole of C₄H₁₀ = produces 4 moles of CO₂

0.124 mole of C₄H₁₀ = produces 4×0.124=0.496 moles of CO₂

Now we calculate the volume for the carbon dioxide gas at the given pressure and temperature as:

V = (0.496)(0.082)(295.15) / (1.20) = 14.4 L

Hence required volume of CO₂ is 14.4 L.

Given: number of mole of tungsten = 4.4 moles

Constant: Molar mass of tungsten = 183.8 g/mol

Substitute these values into equation 2

Therefore,

mass of tungsten = 4.4×183.4

mass of tungsten = 806.96 g

809.6g is your answer

Answer:

1 mole of tungsten =184 g

4.4 mole of tungsten =184×4.4=809.6g
