You are asked by your teacher to buy 10 mol of distilled water from a shop where small bottles each containing 20 g of such water are available . How many bottles will you buy ? |
|
Answer» Solution :Molecular mass of water `(H_(2)O)= 18 `. `THEREFORE` 10 MOL of distilled water = `18 xx 10= 180` g . Because 20 g distilled water is contained in 1 bottle , 180 g of distilled water is contained in `(180)/(20)` BOTTLES = 9 bottles . `therefore` number of bottles to be bought = 9 . |
