Answer:

153.56g

Explanation:

Number of moles = mass/molar mass

To get the number of moles of the molecule, we divide the number of molecules contained by Avagadro's number, which is 6.02 × 10^23 molecules.

moles = 4.12 × 10^24 ÷ 6.02 × 10^23

number of moles = 0.684 × 10^(24-23)

number of moles = 0.684 × 10^(1)

number of moles = 6.84mol

If the molar mass of the molecule is 22.45 g/mol, the mass of the molecule can be calculated thus:

mass = moles × molar mass (MM)

mass = 6.84 × 22.45

mass = 153.558

mass = 153.56g

What is the average velocity of atoms in 1.00 mol of argon (a monatomic gas) at 275 K? For m, use 0.0399 kg. (1 point)
valentinak56 [21]

What is the average velocity of atoms in 1.00 mol of argon (a monatomic gas) at 275 k for m, use 0.0399kg

Answer: The average velocity of the atoms 847.33 m/s.

Explanation:

Moles of the neon = 1.00

Temperature of the gas : 288 K

Mass of the gas = 0.01000

R = 8.31 J/mol K

The average velocity of the atoms 847.33 m/s.

Why do you think forensic scientists are so careful that the tests they do are sensitive, reproducible, and specific?
mario62 [17]

Critical Thinking Questions

1. Why do you think forensic scientists are so careful that the tests they do are sensitive, reproducible, and specific? What might happen if they were less careful about this?

They have to be careful to ensure as much accuracy as possible.

2.Which type of evidence do you think is most useful in an investigation? Why?

Physical evidence would probably be most important because it is the best way to connect someone directly with that crime.

3.Why do you think that forensic scientists continue to look for class characteristics given their limitations?

Class characteristics are good in court because it provides details of different aspects of the crime.
