Answer:  the temperature of the gas

Explanation: The ideal gas law has arrived from the combination of four laws:

1) Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

P\propto \frac{1}{V}     (At constant temperature and number of moles)

2) Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

V\propto T    (At constant pressure and number of moles)

3) Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.

P\propto T     (At constant volume and number of moles)

4) Avogadro's Law: This law states that volume is directly proportional to the number of moles of the gas at constant pressure and temperature.

V\propto n   (At constant temperature and pressure)

According to ideal gas law,

PV=nRT

where,

P = pressure of the gas

V = volume of the gas

T = temperature of the gas

n = number of moles of gas

R = Gas constant

Thus to calculate the gas constant we need to know the temperature of gas.

What mass of oxygen is needed to burn 4g of hydrogen, given the equation below
aleksandrvk [35]

32g of oxygen is required to burn 4g of hydrogen.

Define molecular mass.

A specific molecule's mass is expressed in daltons and is known as the molecular mass (m) (Da or u). Due to the varying isotopes of an element that they contain, multiple molecules of the same substance can have distinct molecular weights.

The total atomic mass of every atom in a molecule, calculated using a scale with hydrogen, carbon, nitrogen, and oxygen having atomic masses of 1, 12, 14, and 16, respectively. For instance, water has a molecular mass of 18 (2 + 16), which consists of two hydrogen atoms and one oxygen atom. known also as molecular weight.

In ,2H2+O2-----> 2H2O

H 2 molecules have a mass of 2 g/mol.

The molecular weight of oxygen is 32 g/mol.

When the chemical equation is balanced,

To totally react, 32 g of oxygen are needed for every 22=4 g of hydrogen.

A eraser has a mass of 4g and a volume of 2cm3 what is it’s density
sladkih [1.3K]

Answer:

<h3>The answer is 2.0 g/cm³</h3>

Explanation:

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

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

From the question

mass = 4 g

volume = 2 cm³

We have

density =  \frac{4}{2}  \\

We have the final answer as

<h3>2.0 g/cm³</h3>

Hope this helps you
