The density of the metal in units of grams per milliliter is 11.31 g/mL

<h3>What is density? </h3>

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

<h3>How to determine the density of the metal </h3>

The following data were obtained from the question:

  • Mass of metal = 23.7412 g
  • Volume of water = 25 mL
  • Volume of water + metal = 27.1 mL
  • Volume of metal = 27.1 – 25 = 2.1 mL
  • Density of metal =?

Density = mass / volume

Density of metal = 23.7412 / 2.1

Density of metal = 11.31 g/mL

A sample of gas has a volume of 2.4 L and a pressure of 1.2 atm. What would the pressure of the same gas sample be if the volume
algol [13]

<u>Answer:</u>

The correct answer option is 1.6 atm.

<u>Explanation:</u>

We know that there is a sample gas which has a volume of 2.4 L with a pressure 1.2 atm and we are to find the pressure of the same gas sample if its volume is reduced to 1.8 L at a constant temperature.

We will apply the Boyle's law here which states that the "pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature".

<em>P_1V_1=P_2V_2</em>

Substituting the values in the formula to get:

P_2=\frac{1.2*2.4}{1.8} \\\\P_2=1.6

Therefore, the pressure of the same gas sample will be 1.6 atm if the volume is reduced to 1.8 L at a constant temperature.

The gas in a balloon has a volume of 2 Lat a temperature of 301 K. What will be the final temperature (in K) when the volume exp
Blizzard [7]

Answer:

Final temperature = 1279.25 K

Explanation:

We can solve this using the formula for Charles law since we are given volume and temperature.

From Charles law, we know that;

V1/T1 = V2/T2

Where;

T1 is the initial temperature

V1 is the initial volume

T2 is the final temperature

V2 is the final volume

We are given;

V1 = 2 L

T1 = 301 K

V2 = 8.5 L

Thus, making T2 the subject, we have;

T2 = V2•T1/V1

Plugging in the relevant values;

T2 = 8.5 × 301/2

T2 = 1279.25 K
