Formula : BaI₂. <span>barium iodide</span>
Methane composes most of the natural gas.
To work it out, you divide 240 by 100 to work out 1% of it, then multiply that by 95 to work out 95% of it. So
(240/100) * 95 = 228mL
The answer is (B) non metals are not very good at coducting electricity.
Hope this helps :).
