Describe the preparation of
2.ool of o. 108M Bacl2 from
Bacl2.2HO (244.3 /mol)

We have to weigh 52.8 g of BaCl₂·2H₂O, add it to a 2.00 L flask and add water until reaching the final volume.

Explanation:

Describe the preparation of 2.00 L of 0.108 M BaCl₂ from BaCl₂·2H₂O. (244.3 g/mol).

Step 1: Calculate the moles of BaCl₂

We need to prepare 2.00 L of a solution that contains 0.108 moles of BaCl₂ per liter of solution.

2.00 L × 0.108 mol/L = 0.216 mol

Step 2: Calculate the moles of BaCl₂·2H₂O that contain 0.216 moles of BaCl₂

The molar ratio of BaCl₂·2H₂O to BaCl₂ is 1:1. The moles of BaCl₂·2H₂O required are 1/1 × 0.216 mol = 0.216 mol.

Step 3: Calculate the mass corresponding to 0.216 mol of BaCl₂·2H₂O

The molar mass of BaCl₂·2H₂O is 244.3 g/mol.

0.216 mol × 244.3 g/mol = 52.8 g

We have to weigh 52.8 g of BaCl₂·2H₂O, add it to a 2.00 L flask and add water until reaching the final volume.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
