Find the Molarity of 6.25 grams of barium nitrate dissolved in 250 mL solution.

0.0956 M

Explanation:

Step 1: Calculate the moles corresponding to 6.25 g of barium nitrate (solute)

The molar mass of barium nitrate is 261.34 g/mol.

6.25 g × 1 mol/261.34 g = 0.0239 mol

Step 2: Convert the volume of solution to liters

We will use the conversion factor 1 L = 1000 mL.

250 mL × 1 L/1000 mL = 0.250 L

Step 3: Calculate the molarity of the solution

The molarity is equal to the moles of solute divided by the liters of solution.

M = 0.0239 mol / 0.250 L = 0.0956 M

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.
