Brainliest A 54.6 mL sample of HCl is titrated with NaOH. If 26.5 mL of 0.255 M NaOH is needed to reach the endpoint, what is the concentration (M) of the HCl solution?

NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)

Consider the following unbalanced equation for the combustion of hexane: αc6h14(g)+βo2(g)→γco2(g)+δh2o(g) part a balance the equation. give your answer as an ordered set of numbers α, β, γ, use the least possible integers for the coefficients. α α , β, γ, δ = nothing request answer part b determine how many moles of o2 are required to react completely with 5.6 moles c6h14. express your answer using two significant figures. n n = nothing mol request answer provide feedback
