Two of the stable isotopes of mercury are 198hg and 202hg. these isotopes emit slightly different wavelengths of light, 546.07532nm and 546.07355nm, respectively. to identify which isotopes are included in a sample of mercury, we can shine the light it emits on a diffraction grating with a screen 4 m away. how many lines per centimeter are necessary in the diffraction grating for the first-order bright fringes of the two wavelengths to be 1.6 cm apart on the screen?

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
