Question

10g bacl2 is dissolved in 90g water. then density of solution is 1g/ml. calculate mass/ volume%

Answer 1

hi brother here your answer it is 1.8

Because water has its density maximum at 4°C, the waters of deep lakes (and of the oceans) usually stay around 4°C at all times of the year . In the summer this will be the coldest water, but in the winter, the surface waters lose heat to the atmosphere and if they cool below 4°, they will be colder than the more dense waters below.

brother I keep more effort on ANSWER your question it take more time to find it and type it
