Give a method to measure size of the atom using Avogadro hypothesis?
One way to measure the size of an individual atom using Avogadro's hypothesis is to calculate the volume occupied by one mole of the element. By dividing Avogadro's number (6.022 x 10^23) by the density of the element, you can determine the volume of one mole of atoms. Finally, by dividing this volume by Avogadro's number, you can find the approximate volume occupied by a single atom.
How many moles of potassium nitrate contain 8.68 x 1020 KNO3 formula units?
To find the number of moles of potassium nitrate (KNO3) from the given formula units, we use Avogadro's number, which is approximately (6.022 \times 10^{23}) formula units per mole. We can calculate the moles by dividing the number of formula units by Avogadro's number: [ \text{Moles of KNO3} = \frac{8.68 \times 10^{20}}{6.022 \times 10^{23}} \approx 0.00144 \text{ moles} ] Thus, there are approximately 0.00144 moles of potassium nitrate in 8.68 x (10^{20}) formula units.
How many weeks are there is 273 days?

How do you find the number of bacteria?
To know the number of bacteria is impossible but approximate to approximate number can be calculated by using electron microscope. To find the exact number is impossible because bacteria keeps on dividing every 5-10 minutes.
Approximate number of islands of Philippines?
Approximately, the Philippines has 7,100 islands. But to be exact, it has a total number of 7,107 islands.
What is 125 as an approximate number of tens?
To convert 125 into an approximate number of tens, you divide it by 10. This gives you 12.5, which can be rounded to 13 when approximating to the nearest whole number. Therefore, 125 is approximately 13 tens.
What is the approximate square root of 79 to the nearest whole number?

How many silver dimes in a pound?
There are approximately 90 silver dimes in a pound. Each silver dime weighs about 2.5 grams, and since there are about 453.6 grams in a pound, dividing that by the weight of a dime gives the approximate count. However, the exact number can vary slightly depending on the condition and wear of the coins.
How dividing by decimal is different from dividing by whole number and how it is similar?
Dividing by decimal is different from dividing by whole number as you have to multiply by a number to remove the decimal.
What is the reciprocal of 13.33?
The reciprocal of a number is found by dividing 1 by that number. For 13.33, the reciprocal is 1 / 13.33, which is approximately 0.075. Therefore, the reciprocal of 13.33 is about 0.075.
