Answer:

The new volume is 66.3 mL

Explanation:

Boyle's law states that pressure and volume are inversely proportional, and that P1V1=P2V2

P1 = 0.428 atm

P2=1.55 atm

V1 = 240 mL

V2 = ??

(0.428)(240)=(1.55)(V2)

102.72 = 1.55x

x = 102.72/1.55 = 66.27 mL.

You can practice converting between the mass of a solution and mass of solute when the mass percent concentration of a solution
LUCKY_DIMON [66]

<u>Answer:</u> The mass of solution having 768 mg of KCN is 426.66 grams.

<u>Explanation:</u>

We are given:

0.180 mass % of KCN solution.

0.180 %(m/m) KCN solution means that 0.180 grams of KCN is present in 100 gram of solution.

To calculate the mass of solution having 768 mg of KCN or 0.786 g of KCN   (Conversion factor:  1 g = 1000 mg)

Using unitary method:

If 0.180 grams of KCN is present in 100 g of solution.

So, 0.768 grams of KCN will be present in = \frac{100g}{0.180g}\times 0.768=426.66g of solution.

Hence, the mass of solution having 768 mg of KCN is 426.66 grams.

Which is not a reason why mass of an atom is expressed in atomic mass units rather than in grams?
Tasya [4]
What are your answer choices? Scientists express the weight in AMU’s so that they can easily think about the weight of the atom. If it is expressed in grams, they’re constantly dealing with a weight that’s around 10^-24 grams, which is hard to deal with.
