pishuonlain [190]
Since you didn't give the actual volume (or any of the experimental values) I can only tell you how to do it. Do the calculation using the real (determined) volume of the flask. Then, re-do the calculation with v = 125ml. Take the two values and calculate % error; m = measured vol; g = guessed vol. 

<span>[mW (m) - mW (g)]/mW (m) x 100% </span>

<span>(they want % error so, if it is negative, just get rid of the sign) </span>

choli [55]

Answer: $46.98

Explanation:

The distance to drive to Los Angeles from San Francisco is 405 miles. Since the car get 25 miles per gallon of gas, for 405 miles, the car will use:

= 405/25 = 16.2 gallons

Since the cost of gasoline is $2.90 a gallon and the car will use 16.2 gallons. The cost will be:

= $2.90 × 16.2 gallons

= $46.98
