Answer:

The answer to your question is: density = 0.993 g/ml

Explanation:

Data

mass beaker empty = 29.3 g

volume of liquid = 15 ml

mass beaker + liquid = 44.2 g

Formula

density = mass / volume

Process

mass of liquid = 44.2 - 29.3

= 14.9 g

density = 14.9 / 15

= 0.993 g/ml

What is the density of an object with a mass of 60 g and a volume of 2 cm3?

Alexxx [7]

Answer:

<h3>The answer is 30 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass = 60 g

volume = 2 cm³

We have

$density = \frac{60}{2} \\$

We have the final answer as

Two samples of potassium iodide are decomposed into their constituent elements. The first sample produced 13.0 g of potassium an

Cerrena [4.2K]

Answer:

79.4 kg

Explanation:

The formula for potassium iodide is:-

$KI$

This means that they are present in the same mole ration, i.e. 1 : 1

Also for 2 samples, the ratio of the masses must be equal .

So,

$\frac{Mass\ of\ potassium\ in\ sample\ 1}{Mass\ of\ Iodine\ in\ sample\ 1}=\frac{Mass\ of\ potassium\ in\ sample\ 2}{Mass\ of\ Iodine\ in\ sample\ 2}$

Thus,

Mass of potassium in sample 1 = 13.0 g

Mass of Iodine in sample 1 = 42.3 g

Mass of potassium in sample 2 = 24.4 kg

Applying in the above formula, we get that:-

$\frac{13.0\ g}{42.3\ g}=\frac{24.4\ kg}{Mass\ of\ Iodine\ in\ sample\ 2}$

Mass of iodine in sample 2 = 79.4 kg

The volume of a sample of gas is 0.5 L and the pressure is 0.98 atm. The volume is increased to 1.0 L. Show the set

meriva

Given,

P1 = 0.98 atm

V1 = 0.5 L

V2 = 1.0 L

P2 = ?

Solution,

According to Boyle's Law,

P1V1 = P2V2

0.98 × 0.5 = 1.0 × P2

P2 = 0.98 × 0.5 × 1.0

P2 = 0.49 atm

Answer - The new pressure is 0.49 atm.
