An aqueous nitric acid, HNO3, solution is 29.94% by mass HNO3. The solution has a density of 1.182 g/ml. What are the molality, molarity and mole fraction of HNO3 in this solution?
Will rate ASAP . I've worked out the problem using 29.94 grams of HNO3 and then 70 grams for water (100g-29.9g=70). However, I am wondering about the density given in this problem (1.182). How does that come into play?
A green leaf has surface area 2.20 cm^2. If solar radiation is 1190 W/(m^2) , how many photons strike the leaf every second? Assume three significant figures and an average wavelength of 504 nm for solar radiation.
Calculate the amount of work done against an atmospheric pressure of 1.00 atm when 500.0 g of zinc dissolves in excess acid at 30.0°C. Zn(s) + 2H+(aq) → Zn2+(aq) + H2(g)
