A seven molar solution of koh in water contains 40% by weight of koh the density of koh is
Answers
please check the solution...
to calculate the density of koh solution...
A 6.90 M solution contains 6.90 mol of KOH in 1000 cm3 of the solution.
Mass of 6.90 mol of KOH = 690 H 56 = 386.4 g
A 30% solution contains 30g of KOH present in = 100 g of solution
∴ 386.4 g of KOH is present in = (100 x 386.4 g) / 30 = 1288 g of solutions
Density of KOH solution = (Mass / volume) = 1288 / 1000 =1.288 g/cm-3
Answer:
In theoretical physics, it is often important to consider gauge theory that admits many physical phenomena and "phases", connected by phase transitions, in which the vacuum may be found.
