Ronch [10]

Answer:

$P(GR)=\frac{2}{13}$

Step-by-step explanation:

Number Of Red Balls=6

Number Of Green Balls=4

Number Of blue Balls=3

Total Number Of Balls=6+4+3=13

Notice that the two balls are picked without replacement. In this case, the total number of balls always decreases.

P(first ball will be green and the second will be red)

$=\dfrac{4}{13} X \dfrac{6}{12} \\=\dfrac{2}{13}$

A liquid oral concentrate of morphine sulfate contains 2.4 g of morphine sulfate in a 120-mL bottle. Calculate the concentration

MrMuchimi

Answer:

20 mg/ml.

Step-by-step explanation:

We have been given that a liquid oral concentrate of morphine sulfate contains 2.4 g of morphine sulfate in a 120-mL bottle.

$\text{Concentration of morphine sulfate on g/mL basis}=\frac{\text{2.4 g}}{\text{120 ml}}$

To convert the concentration of morphine sulfate on a mg/mL basis, we need to convert 2.4 grams to milligrams.

1 gram equals 1000 milligrams.

$\text{Concentration of morphine sulfate on mg/mL basis}=\frac{\text{2.4 g}}{\text{120 ml}}\times\frac{\text{1,000 mg}}{\text{1 g}}$

$\text{Concentration of morphine sulfate on mg/mL basis}=\frac{2.4\times\text{1,000 mg}}{\text{120 ml}}$

$\text{Concentration of morphine sulfate on mg/mL basis}=\frac{2400\text{ mg}}{\text{120 ml}}$

$\text{Concentration of morphine sulfate on mg/mL basis}=\frac{20\text{ mg}}{\text{ml}}$

Therefore, the concentration of morphine sulfate would be 20 mg per ml.

1/7 divided by what equals 14

posledela

Assume the number we are looking for in n
we want to know the value of n that makes 1/7 divided by n is 14

Transforming this to an equation:
(1/7) / n = 14
this means that:
1/7 = 14n
1 = 7 x 14n
1 = 98n
n = 1/98

Therefore:
1/7 divided by 1/98 will give us 14
