Digoxin is available in a concentration of 0.1 mg/ml. How many ml are required to administer a 75 mcg dose?

Step2247 [10]

Answer : The volume required to administer a 75 mcg dose are, 0.75 mL

Explanation : Given,

Concentration of Digoxin = 0.1 mg/mL

That means, 0.1 mg of Digoxin present in 1 mL of solution.

Mass of dose = 75 mcg = 0.075 mg

Conversion used : (1 mcg = 0.001 mg)

Now we have to determine the volume required to administer a 75 mcg dose.

As, 0.1 mg of Digoxin required in 1 mL of solution

So, 0.075 mg of Digoxin required in $\frac{0.075mg}{0.1mg}\times 1mL=0.75mL$ of solution

Thus, the volume required to administer a 75 mcg dose are, 0.75 mL

If a sample of a different compound decomposes into 0.429 g of carbon and 0.571 g of oxygen, what is its ratio of the mass of o

EastWind [94]

Ratio is the relationship between two number indicating how many times the first number containing the second number.
The ratio of carbon to oxygen is as follows
0.429 :0.571
multiply 1000 to remove the decimals
therefore the ratio of mass of carbon to mass of oxygen =429:571
