Stoichiometry How many moles of sodium sulfate
(Na2SO4 – 142.06 g/mol) will be formed if you start with 186 grams of sodium hydroxide (NaOH – 40.00 g/mol)?

2 NaOH + H2SO4 → 2 H2O + Na2SO4

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

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
