1 ml of 7.5% sodium bicarbonate provides:-
**Core Concept**
Sodium bicarbonate is a widely used medication for various clinical purposes, including the treatment of acidosis, as a local anesthetic, and as a component of intravenous fluids. The concentration of sodium bicarbonate is expressed in terms of its percentage weight by volume, which is essential for accurate dosing.
**Why the Correct Answer is Right**
To calculate the amount of sodium bicarbonate in 1 ml of 7.5% solution, we need to understand that the percentage concentration is based on the weight of the solute (sodium bicarbonate) per unit volume of the solution. In this case, 7.5% means 7.5 grams of sodium bicarbonate per 100 ml of solution. To find the amount in 1 ml, we can calculate it as follows: 7.5 grams/100 ml x 1 ml = 0.075 grams.
