Question

If two tablespoonfuls of a 10% w/v povidone–iodine solution were diluted to 1 quart with purified water,

Answer 1

Answer:

$1 : 315$

Explanation:

As we know that

one quart is equal to $946.3$ mls

one table spoon is equal to $15$ mls

Therefore, two table spoon is equal to

$2 * 15 = 30$ mls

$Q_1 * C_1 = Q_2 * C_2$

Here,

$Q_1$ & $Q_2$ represents the volume

$C_1$ & $C_2$ represents the concentration

Substituting the given values in above equation, we get -

$30 * 10$% $= 946.3 * X$%

$X$% $= \frac{30 * 10}{946.3}$

$X$% $= 0.317$ %

$0.317$ % $= 100 : 0.317$

$1 : 315$
