<h2>Answer</h2>

2.626984127 m

<h2>Explanation:</h2><h2></h2>

You have to know the equation that relates wavelength, frequency, and velocity (it's like speed but a bit different).

v = f x λ

where:

v = velocity

f = frequency

λ = Wavelength

Rearrange to make λ subject:

λ = v / f

We've been given 331 as the speed, 126 as the frequency. Sub it into the equation:

331 / 126 = 2.626984127 m

How many atoms are found in 4.75 moles of Fe?
aliya0001 [1]

Answer:

The answer to your question is below

Explanation:

a)

Number of atoms = ?

moles of Fe = 4.75

-Use proportions to solve this problem

                            1 mol of Fe --------------------- 6.023 x 10²³ atoms

                          4.75 moles  ---------------------  x

                            x = (4.75 x 6.023 x 10²³) / 1

                            x = 2.86 x 10²⁴ / 1

  Number of atoms = 2.86 x 10²⁴

b)

Number of moles = ?

moles of 1.058 moles of H₂O

I think this question is incorrect, maybe you wish to know the number of atoms or grams of H₂O.

c)

Number of atoms = ?

moles of Fe = 0.759

                       1 mol of Fe ------------------ 6.023 x 10²³ atoms

                       0.759 moles ---------------  x

                        x = (0.759 x 6.023 x 10²³) / 1

                        x = 4.57 x 10²³ / 1

Number of atoms of Fe = 4.57 x 10²³ atoms

d)

Number of molecules = ?

moles of H₂O = 3.5 moles

                          1 mol of H₂O ------------------ 6.023 x 10²³ molecules

                         3.5 moles       ------------------   x

                          x = (3.5 x 6.023 x 10²³) / 1

                          x = 2.11 x 10²⁴ molecules

Number of molecules = 2.11 x 10²⁴

One isotope of Br has a half-life of 16.5 hours. How much of a 2.00 gram sample remains at the end of 1.00 day?
valina [46]

Answer:

half life=16.5hrs

sample=2g

total time=1day=24hrs

no. of half lives=total time/half life

no. of half lives=24hrs/16.5hrs=1.45approx1.5

sample left=1/2n=1/2[1.5]=0.707gapprox
