What is the molarity when 40 grams of HF is added to water to make a 500 ml solution? CzHg + 502 --> 3CO2 + 4H20 M (molarity) = moles/Liters
1000 ml= 1L
molar mass in grams = 1 mole of substance

In which of these cases are the two wave points considered to be in phase with each other?

In the millikan oil drop experiment they determined that every drop had a charge which was a while number multiple of -1.60x10^-19. if a drop has a total charge of -9.60x10^-19 then how many excess electrons are contained within the drop?

How are isotopes of the same element alike?
