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

How volcanoes are created

Lera25 [3.4K]

A volcano is created when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Hot ash and gases are thrown into the air.

Darina [25.2K]

Explanation:

Given parameters:

Initial volume V1 = 200cm³

Initial temperature = 60°C

Final temperature = 120°C

Unknown:

Final volume = ?

Solution:

According to Charles law, at constant pressure, the volume of a given mass of gas is directly proportional to temperature.

mathematically;

$\frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }$

1 and 2 are the initial and final states

V is the volume and T is the temperature

convert the temperature to kelvin

T1 = 60 + 273 = 333K

T2 = 120 + 273 = 393K

Input the parameters;

$\frac{200}{333} = \frac{V_{2} }{393}$

final volume is 236cm³
