One mole of a chemical element contains approximately 6.02 × 1023 atoms. How many atoms are present in 4.6 × 104 moles of oxygen
Paraphin [41]

Answer:

B. 2.77 · 10^28

Step-by-step explanation:

The total number of atoms is ...

(6.02·10^23 atoms/mol)·(4.6·10^4 mol) = (6.02·4.6)·10^(23+4) atoms

≈ 27.7·10^27 atoms

≈ 2.77·10^28 atoms . . . . . . put in scientific notation form

_____

Scientific notation has one non-zero digit to the left of the decimal point and the exponent adjusted accordingly.

__

Your calculator can help you figure this out. If necessary, put the display into scientific notation mode. (For numbers this size, it is usually not necessary.)

Convert 1.50 micrometers^2 to m^2. Show your solution.
Vadim26 [7]

Here is the solution for the problem:

<span>1m * 1m = 1m² </span><span>
<span>1m = 1,000,000µm = 1 x 10^6µm </span>
<span>1 x 10^6µm * 1 x 10^6µm = 1m² </span>
<span>1x10^12µm² = 1m² (Now, divide both sides by 1x10^12). </span>
<span>1x10^12µm² / (1 x 10^12) = 1m² / (1 x 10^12) </span>
<span>1µm² = 0∙000 000 000 001 m² (x both sides by 1.5). </span>
<span>1.5µm² = 0∙000 000 000 0015 m² </span>
1.5µm² = 1∙5x10^-12 m²</span>

So 1.50 micrometers^2 is equal to 1.5 x 10^-12 m². I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

In probability problems, look out for the word OR and AND.

OR means adding the probability
AND means multiplying the probability

P(a) = P(jack) + P(queen) + P(king) = (4/52) + (4/52) + (4/52) = 12/52 = 3/13

P(b) = [P(9) + P(10) + P(jack)] × P(red) = [(4/52) + (4/52) + (4/52)] × (26/52)
P(b) = (12/52) × (26/52) = 3/26

P(c) = 13/52 = 1/4

P(d) = P(a diamond) + P(a heart) + P(a spade) =  (13/52) + (13/52) + (13/52) = 3/4

val has 2 hours to finish a slide presentation. it takes her 1 over 6 hour to create each slide. will val have enough time to cr
vitfil [10]

Answer:

Yes she can.

Step-by-step explanation:

Val can make 6 slides in an hour.

1/6 * 60 minutes = 10 minutes. per slide

10 20 30 40 50 60 gives you six sldes, 1 every ten minutes.

=====================

In one hour, she can produce 6 slides.

In two hours, she can produce 12 slides (2 * 6 = 12)

Since she only needs 1 hour and 40 minutes to produce 10 slides, she is under her time limit of 2 hours.
