Answer:

<u>2.256 x 10 to the power of 25</u>

Step-by-step explanation:

There are 3.76 x 10 to the power of 22 atoms in 1 gram of oxygen

So, there are x atoms in 600 grams of oxygen

Using the ratio and proportional

So, the number of atoms = 600 * 3.76 x 10 to the power of 22 =

$= 6*10^2 * 3.76 * 10^{22}\\=6*3.76 * 10^2*10^{22}\\=22.56 * 10^{24}\\=2.256 * 10 * 10^{24}\\=2.256 * 10^{25}$

So, the answer in scientific notation as A.BCD x 10 to the power of E

Will be <u>2.256 x 10 to the power of 25</u>

PLEASE HELP ITS MATH THANK YOUUUU

NISA [10]

Answer: 10 meters

Explanation:

29 cm : blank meters

So how do we get from 348 cm to 29 cm?

To figure this out we divide.

348 divided by 28 = 12

we divided by 12 so we do the same with 120

120 divided by 12 = 10

So that’s the answer.

I hope this makes sense and helps you :)
