Plz help can mechanical waves travel through objects?!?!?

1 answer:

7 0

Answer:

Mechanical waves travel through matter, causing it to vibrate, expand and contract, move up and down, side to side, or in circles. They include water waves, sound waves, and seismic waves. ... They all travel at the same speed — the speed of light — in a vacuum, but when they come into contact with matter, they slow down.

Misha Larkins [42]

Answer:

0.137 M NH3

Explanation:

First divide the mass of NH3 by the molar mass of NH3, and then divide by the volume to get molarity.

0.583 g / 17.031 g/mol = 0.0342 mol NH3

0.0342 mol NH3 / 0.250 L = 0.137 M NH3
