How many ions are present in 9.4g of pottasium oxide K2O? (K=39 ,O=16) (Avogadros constant=6.0*10^23/mol)
elena-14-01-66 [18.8K]
1) k2O = 2K(1+) + O(2-)

This is, every molecule of K2O consists of three ions (2 of K 1+, and one of O 2-)

2) Caluclate the number of moles of K2O

- molar mass of K2O = 2*39 + 16 = 94 g/mol
- n = mass / molar-mass = 9.4g / 94 g/mol = 0.1 mol

3) Multiply by 3 to have the number of moles of ions: 3 *0.1 mol =  0.3 mol of ions.

4) Multiply by Avogadro's number to obtain the number of ions"

0.3 mol * 6.0*10^23 =1.8 * 10^23 ions.

Answer: 1.8*10^23 ions

Verizon [17]

Answer: The loose objects will tend to move to the right inside the car.

Explanation:

The options include:

A. The loose objects will tend to move to the left inside the car.

B. The loose objects will tend to move to the right inside the car.

C. The loose objects will tend to move toward the front of the car.

D. The loose objects will tend to move toward the back of the car.

Based on the question, we are informed that Mary is driving on a straight road and then a deer jumps in front of her, which made her turn her car sharply to the left.

The loose objects inside the car will move towards the opposite direction. Since Mary made a left turn, the loose objects in the car would move to the right.
