Question

Ketamine, sometimes used as an adjuvant Two general anesthesia, it’s available as a 10.0% (w/v) solution. Calculate the mass of ketamine in 1.50 mL of this solution. Be sure your answer has a unit symbol and is rounded to the correct number of significant digits.

Answer 1

The mass of ketamine in 1.50 milliliters of a 10.0% (w/v) solution is 0.00015 grams.

Given that the ketamine solution is 10.0% (w/v) and is available as a 10.0% (w/v) solution, this means there are 10.0 grams of ketamine in 100 milliliters of the solution.

First, convert the volume from milliliters to liters:

1.50 milliliters = 0.0015 liters

Now, use the formula:

Mass = Volume × Concentration

Mass = 0.0015 liters × (10.0 g/100 mL)

Mass = 0.0015 liters × 0.1 g/mL

Mass = 0.00015 grams

Therefore, the mass of ketamine in 1.50 milliliters of a 10.0% (w/v) solution is 0.00015 grams.

Answer 2

`0.15g\text{ of ketaime}`

Step-by-step explanation:

Here, we want to calculate the mass of ketamine in 1.50 mL of the solution

A 10% w/v means there are 10 g iof ketamine n 100 ml of solution

Thus, if we have 10 g in 100 ml, there will be x g in 1.5 ml

10g in 100 ml

xg in 1.5 ml

By cross multiplication, we have:

`\begin{gathered} 10\text{ }*\text{ 1.5 = x}*\text{ 100} \\ x\text{ = }(15)/(100) \\ x\text{ = 0.15g} \end{gathered}`
