Convert 1.55 x 10^24 ATOMS OF CARBON TO MOLES OF CARBON

Answers

Answer:

2.57 moles of carbon

Explanation:

1 mole = 6.023x10^23 (this is called avogadro's number)

1/6.023x10^23

1.55x10^24 = 1.55x10^24/6.023x10^23 = 2.57 moles

this means, 1.55x10^24 atom contains 2.57 moles of carbon

what is the volume, in liters, of 5.500 mol of C3H3 gas at STP

Answers

Answer:

123.2 Liters.

Explanation:

At STP (T = 273K & P = 1atm), one mol of any gas will occupy 22.4 liters.

With the above information in mind, we can calculate how many liters would 5.500 mol of gas occupy:

5.500 mol * 22.4 L / mol = 123.2 L

So 5.500 moles of C₃H₃ would have a volume of 123.2 liters at STP.

Answer:

A. Bees bringing pollen from the flower of one plant to the flower of another plant.

Explanation:

Genetic diversity in organisms is enhanced by the process of sexual reproduction due to the meiotic process that the participant organisms undergo to produce gametes. A process unique to meiosis called CROSSING OVER ensures that the alleles of genes are recombined in the GAMETE or sex cells.

According to this question, POLLINATION, which is the transfer of pollen from a male flower to a female one, will lead to sexual reproduction via fertilization. However, a cross-pollination, which requires a pollinator like the bees in this question will ensure the most genetic diversity among the offsprings.

Air in a closed cylinder is heated from 15°C to 36°C. If the initial pressure is 1000 torr, determine what is the final pressure? *

Answers

Answer:

1072 torr

Explanation:

To answer this problem we can use Gay-Lussac's law, which states:

P₁T₂=P₂T₁

Now we convert the given temperatures into K:

T₁ = 15°C ⇒ 15+273.16 = 288.16 KT₂ = 36°C ⇒ 36+273.16 = 309.16 K

We input the data:

1000 torr * 309.16 K = P₂ * 288.16 K

And solve for P₂:

P₂ = 1072 torr

What's the mass in grams of 0.334 moles of sucrose (C12H22O11)?

Answers

Answer:

114.23g

Explanation:

Mass = xg

Mole = 0.334 mol

Molar mass of Sucrose

(C = 12, H = 1, O = 16)

C12H22O11

(12×12)+(1×22)+(16×11)

144 + 22 + 176

342g/mol

Mass = No of mole × Molar mass

Mass = 0.334 × 342

Mass = 114.228

Mass ≈ 114.23g

i need help with this ASAP please i don’t understand this

Answers

Answer:

750 mmHg

Explanation:

From the question given above, the following data were obtained:

Partial pressure of CO₂ (Pₐ) = 250 mmHg

Partial pressure of N₂ (P₆) = 375 mmHg

Partial pressure of He (P꜀) = 125 mmHg

Pressure of the mixture (Pₜ) =?

The pressure of the mixture of the gases can be obtained as follow:

Pₜ = Pₐ + P₆ + P꜀

Pₜ = 250 + 375 + 125

Pₜ = 750 mmHg

Therefore, the pressure of the mixture of the gases is 750 mmHg
