if 100. ml of 0.200 m na2so4 is added to 200. ml of 0.300 m nacl, what is the concentration of na ions in the final solution? assume that the volumes are additive.

the answer would be b i believe

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

it is the most commonly accepted one

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa
