A collection of 0.002823 grams of hydrogen gas over water in an eudiometer at 23 degrees celsius. The atmospheric pressure is 794 of mmHg. What volume of dry hydrogen gas would be collected?

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer
