A binary ionic compound is composed of ions of two different elements. One of which is a metal, and the other a non-metal
Answer:
The concentration is 6.42×10^-4 M
Explanation:
Number of moles trichloroethylene = pressure × volume/Henry's constant = 0.00301×0.21/0.00985 = 0.0642 mol
Volume of mixture = 100 L
Concentration of trichloroethylene = number of moles of trichloroethylene/volume of solution = 0.0642/100 = 6.42×10^-4 M
Answer:
We mostly use Kilograms and grams to measure mass =)
