The patient needs 1000 ml of 5% (w/v) glucose solution
i.e 1000 ml x 5 g/ 100 ml
where the stock solution is 55% (w/v) = 55 g / 100 ml
So, 1000 ml x 5 g / 100 ml = V (ml) x 55 g / 100 ml
V = 1000 x (5 / 100) / (55 / 100) = 5000 / 55 = 90.9 ml
∴ the patient needs 90.9 ml of 55% (w/v) glucose solution
The milk of magnesia is a
suspension of magnesium hydroxide in water, which is a strong base that is used
to neutralize excess stomach acid. The presence of stomach acid or hydrochloric
acid (HCl) that is known to be a strong acid will react with the strong base and
neutralization reaction occurs since conjugate partners produced negligible
strength where the products are a salt and water.
It avoids confusion through scientists. If you think, they could be practicing or studying in varying countries and something uniform for science avoids all confusion!
