Consider a solution initially containing 0.400 mol fluoride
anion and 0.300 mol of hydrogen fluoride (HF). How many moles of
hydrogen fluoride are present after addition of 70.0 mL of 0.600M
HCl to this solution?
A mixture of fuel containing 0.530 mol CH4/mol, 0.300 mol
C3H8/mol, and 0.170 mol C5H12/mol at 59.0°C and 139 kPa (gauge)
enters a furnace at a rate of 85.0 L/min where it reacts with 10.0%
excess air. Determine the volumetric flow rate of air to the
furnace in SCFM (standard cubic feet per minute) by following the
steps below. Assume that the gases behave ideally.
What is the molar flow rate of fuel entering the furnace?

A 360.0 ml buffer solution is 0.130 mol/L in HF and 0.130 mol/L in NaF.
Part A : what mass of NaOH could this buffer neutralize before the PH rises above 4.00?
Part B: If the same volume of the buffer was 0.370mol/L in NaF, what mass of NaOH could be handled before the pH rises above 4.0?
the Ka of HF is 3.5*10^-4 this is all the information given, I can look up more ka or...
A solution is made by dissolving 0.0100 mol of HF in 1.00 kg of
water. The solution was found to freeze at –0.0236 °C. Calculate
the value of i and estimate the percent ionization of HF in this
solution.
i =____ so HF is ______
