6. A 25-gram sample of halite was placed in a jar with five other mineral samples and water. The jar was shaken vigorously for 5 minutes. The halite sample was then found to have a mass of 15 grams . What was the rate of weathering of the halite sample? (1) 0.50g/min (2) 2.0g/min (3) 3.0g/min __ (4) 10.0g/min 6

## Step 1: Determine the initial and final mass of the halite sample### The initial mass of the halite sample is 25 grams, and the final mass after shaking is 15 grams.## Step 2: Calculate the mass loss of the halite sample### Subtract the final mass from the initial mass: .## Step 3: Determine the duration of the shaking process### The duration is given as 5 minutes.## Step 4: Calculate the rate of weathering### The rate of weathering is the mass loss divided by the time: .
