A chemist is using 336 milliliters of a solution of acid and water. If 16.4% of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.

Amount of acid = 55.1 mm (Approx)

Step-by-step explanation:

Given:

Amount of solution = 336 mm

Percentage of acid = 16.4%

Find:

Amount of acid

Computation:

Amount of acid = Amount of solution x Percentage of acid

Amount of acid = 336 x 16.4%

Amount of acid = 55.1 mm (Approx)

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
