4.05 kg + 567.95 g + 100.1 g add the correct value using the correct sig figs and or least precise degree of precision. when i did least degree of precision i got 4718.1g, do we need to convert the kg unit to grams before getting the least degree of precision? since i used 100.1 as dop and if i had converted first the dop of 4.05 or now 4050g the dop is now only to the tens place compared to being in the tenths place

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.)
