There are 3.76 x 10 to the power of 22 atoms in 1 gram of oxygen. How many atoms are there in 600 grams of oxygen? Write your an

tatiyna

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>

Find the length of each arc, Round your answas to the nearest tenth. Use 3.14 for

quester [9]

Answer:

58.6 cm;

20.1 m

Step-by-step explanation:

✔️Length of arc = θ/360 × 2πr

Where,

θ = 240°

r = 14 cm

π = 3.14

Plug in the values:

Length of arc = 240/360 × 2 × 3.14 × 14

= 58.6133334 = 58.6 cm (nearest tenth)

✔️Length of arc = θ/360 × 2πr

Where,

θ = 105°

r = 11 m

π = 3.14

Plug in the values:

Length of arc = 105/360 × 2 × 3.14 × 11

= 20.1483334 = 20.1 m (nearest tenth)
