Question

what is the wt of hcl if the ph is 2 & in 500ml

Answer 1

Answer:

PH =2

so concentration = -antilog 2

[HCL]

$cocentration \: = {10}^{ - 2} molar$

$molarity = \frac{no \: of \: moles}{vol \: in \: l} \\ {10}^{ - 2} = \frac{x}{500} \\ 5 = x$

So no of moles=5

weight = molecular weight × no.of moles.

weight= 36.46×5

weight=182.3 g.
