Complete the equation to show how many thirds are equivalent to<br> 8/12 = ?/3
anygoal [31]

Answer:

\frac{2}{3}

Explanation:

What we need to do is to convert \frac{8}{12} into a new - but still equal - fraction, one with a denominator of 3. In order to convert a fraction, you either divide or multiply both the denominator and the numerator by the same number.

We know that the answer has to be a fraction with the denominator of 3. Take a look at the denominator of \frac{8}{12} - it's 12. Ask yourself: 12 divided by what number equals 3? That number would 4.

So, divide 8 by 4 as well and you would get 2. Therefore, the numerator would be 2 and the answer is \frac{2}{3}.

How many fluorine atoms are found in 1.92 grams of AsF3?
11111nata11111 [884]
First you need to find out how many moles of AsF3 are in 1.92 grams.  
The molar mass of AsF3 is 131.918 g/mole so  
1.92 g * (1 mole)/(131.918g) = .0146 moles AsF3 


 Each mole of AsF3 has 6.02 x10^23 molecules of AsF3 and each molecule of AsF3 has 3 flourines, so you need to convert from moles to molecules AsF3 to atoms of F 
 0.146 moles AsF3 * (6.02 x 10^23 molecules AsF3)/(1 mole AsF3) * (3 atoms F)/(1 molecule AsF3) = 2.64 x 10^22 atoms F

Diano4ka-milaya [45]
Possibility or highly chances are that the five is going to get pulled because there are two of the fives and five isn't rare, so from the number 9,484,558 the number that would possibly be picked is one of the fives because there are two of the fives and five isn't rare if there is two of them, so the digit that would probably be pulled is one of the fives
