Asample of gas occupies 9.0 ml at a pressure of 500.0 mm hg. a new volume of the same sample is at a pressure of 750.0 mm hg.

is the new pressure smaller or larger than the original?

therefore, is the new volume larger or smaller than 9.0 ml?

what is this new volume?

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

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
