Sllom A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of
pentane, diethylamine, ethanolamine, chloroform, and dimethyl sulfoxide.
The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety
Data Sheets (MSDS), the chemist finds the following information:
liquid
density
pentane
0.63
g/mL
diethylamine
0.71
g/mL
ethanolamine
1.0
g/mL
chloroform
1.5
g/mL
dimethyl sulfoxide
g
1.1
g/mL
Next, the chemist measures the volume of the unknown liquid as 1151. cm^3 and the mass of the unknown liquid as 1.71 kg.
Calculate the density of the liquid. Round your
answer to 3 significant digits.
Given the data above, is it possible to identify
the liquid?
If it is possible to identify the liquid, do so.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
