9.75 x 10^5
A number in scientific notation has the form <em>a x 10^b</em> where
• a is the <em>coefficient</em>
• b is the <em>exponent</em>
Here are the steps to convert a number greater than 1 to scientific notation.
a) Find the coefficient
Put the decimal point after the first digit and drop the trailing zeroes
<u>9.75</u> 000
The coefficient is 9.75
.
b) Find the exponent
Count the number of digits after the first digit.
In 975 000 there are five digits after the 9. Therefore, the exponent is 5.
c) Write the number
We write 975 000 as 9.75 x 10^5.
Answer:
40 g
Explanation:
Find the line labeled KClO3 (which might take you a min, theres a lot of lines here)
Notice that when the line creates a direct point, you can measure the exact temperature needed to dissolve a certain amount (like how they gave 30 degrees and it lined up perfectly with the 10 g line. )
Since its asking for the amount at 80 degrees, all you need to do is trace the line to the 80 degree point, and look at the grams. (notice it made a direct point, so there definitely should be any decimals or guesswork)
By reading the graph, you can tell that at 80 degrees, it dissolves 40 grams, and that is your answer.
Hope this helps :)
