A sample of water contains $1 \times 10^{- 3}$ moles of per $10$ kg of water. Calculate the degree of hardness of water.
$50$ ppm
$500$ ppm
$100$ ppm
$10$ ppm

$10^{4}$ gms of water contain $10^{- 3}$ moles
$10^{6}$ gms of water contain $\frac{10^{- 3}}{10^{4}} \times 10^{6}$ = $0.1$ mole.
$1$ mole has degree of hardness $= 100$ ppm
$0.1$ mole has degree of hardness $= 100 \times 0.1 = 10$ ppm

$10^{4}$ gms of water contain $10^{- 3}$ moles
$10^{6}$ gms of water contain $\frac{10^{- 3}}{10^{4}} \times 10^{6}$ = $0.1$ mole.
$1$ mole has degree of hardness $= 100$ ppm
$0.1$ mole has degree of hardness $= 100 \times 0.1 = 10$ ppm
