Please help me! I'd really appreciate it thanks Show all work, include units, subscripts, and superscripts, correct particle name, etc. as demonstrated in class.

Calculate the Molar mass of magnesium thiotellurite (Mg3TeS5).

Determine the mass of 2.30 moles of KMnO4.

Find the mass of 5.0 x 1020 formula units Mg3TeS5.

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
