Answer : The concentration of the resulting solution will be 0.0872 moles.

Explanation: As the two volumes are given and one of the moles concentration needs to be found.

So, according to the formula :- m_{1} V_{1} = m_{2}V_{2}
 
And here if we consider m_{1} as 0.436 moles and V_{1} as 50 mL then we need to find m_{2} as V_{2} is given as 250 mL.

So, by solving we get m_{2} = (0.436  X   50) / 250 = 0.0872 moles.

Hey there,

Your answer is iii. Brown cows produce white milk. (1 point) <u>and</u> ii. Brown cows never produce chocolate milk. (1 point)

1 hour has 3600 seconds (60*60)

24 hour = 1 day

3600 second * 24 hours =

1 day has 86400 seconds so in four days

why is it less effective to wash an insoluble precipitate with 15 ml of water once than it is to wash the precipitate with 3 ml
MArishka [77]

It is less effective to wash an insoluble precipitate with 15 ml of water once than it is to wash the precipitate with 3 ml of water 5 times because commonly, when you clean an <span>indissoluble precipitate with water, the water will not be completely saturated with contaminates. Therefore, the absorption of the contaminates would lower with each wash, since if you only washed it once with a bigger amount or volume of water, it’d become less contaminated with the wash water but it wouldn’t get rinsed numerous times.</span>
