Question

A label reads: “Gantrisin. 1.5 g in 20 mL. “ how many milliliters are needed to give10.5 g of Gantrisin?

Answer 1

Answer: 140 ml

Explanation:

Hi, to answer this question we have to apply proportions.

1.5 g in 20 mL = the proportion is = 1.5 g/20ml

For 10.5 g:

10.5 g / x ml

Where x is the amount of milliliters for 10.5g of Gantrisin.

So:

1.5 g/20ml =10.5 g / x ml

1.5/20 = 10.5 /x

Solving for x

x = 10.5 / (1.5/20)

x = 140 ml

Feel free to ask for more if needed or if you did not understand something.

Answer 2

140 ml is needed to give 10.5g of Gantrisin

Explanation:

In this question, we are asked to calculate how many milliliters liters will give a certain mass of Gantrisin.

Firstly, from the first values given, we can calculate the value if the density of the liquid.

Mathematically, the value of the density can be calculated by ;

Density = mass/volume = 1.5g / 20ml = 0.075 g/ml

Now for the second part of the question, we have the mass, but we do not know the volume. We can use the calculated density to know this.

We use the formula

volume = mass/density

Volume = 10.5g/(0.075g/ml)

Volume = 140 ml
