Question

Розчин натрій броміду з масовою часткою солі 10% застосовують при розладі нервової системи. Обчисліть масу натрій броміду в ампулі, що містить 10 г даного розчину

Answer 1

Очень простая задача.
m(NaBr)=10г*0,1=1 грамм.

Answer 2

Calculation of Sodium Bromide Mass in the Solution

To calculate the mass of sodium bromide in the given solution, we can use the definition of mass percent concentration. The mass percent concentration of a solution is defined as the mass of the solute divided by the total mass of the solution, multiplied by 100.

The formula for mass percent concentration is:

Mass percent concentration = (mass of solute / total mass of solution) * 100

Given: - Mass percent of sodium bromide in the solution = 10% - Mass of the solution = 10g

Using the formula, we can calculate the mass of sodium bromide in the solution.

Mass percent concentration = (mass of sodium bromide / total mass of solution) * 100

10% = (mass of sodium bromide / 10g) * 100

To find the mass of sodium bromide, we can rearrange the equation:

mass of sodium bromide = (10% * 10g) / 100

mass of sodium bromide = 1g

Therefore, the mass of sodium bromide in the ampoule containing 10g of the given solution is 1g.
