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.)
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

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
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.
