Answer:
4.10x10⁻³g.
4.10 mg.
Explanation:
Hello,
In this case, considering the given number, we can see it has two digits after the first nonzero digit that is four (4) which is also at the third decimal place, it means that the scientific notation has a negative power as it is at the left of the given zeros, therefore it is:
4.10x10⁻³g.
Moreover, since the proper prefix for the factor x10⁻³ is milli, the number with prefix is:
4.10 mg.
Best regards.
Finding the difference in math usually means to subtract to numbers. In the case of your problem though, I think the correct answer would just be 4...
We know that:
speed = distance / time
time = distance / speed
The speed of light is 3 x 10⁸ m/s
Now, we must convert the distance to meters to obtain our answer in seconds. After that, we will multiply it by 1000 to obtain the answer in milliseconds(ms)
1 mile = 5280 ft
2462 miles = 2462 x 5280 = 12999360 ft
1 ft = 12 inches
12999360 ft = 12999360 x 12 = 155992320 in
1 in = 2.54 cm
155992320 in = 155992320 x 2.54 = 396220492.8 cm
1 m = 100 cm
396220492.8/100 = 3962204.928 m
Time = 3962204.928 / 3 x 10⁸
= 0.0132 seconds
1 s = 1000 ms
0.0132 x 1000 = 13.2 ms
The standard molar volume of a gas at STP is 22.4 L for 1 mole of gas at a temperature equal to 273.15 K and a pressure equal to 1.00 atm!
