A given volume of methane diffuses in 20 seconds How long will it take the
same volume of sulphur (IV) oxide to
diffuse under the same condition
(Methane = 16, Sulphur (IV) oxide=64)​

Answers

Explanation:

Relative molecular mass of CH4 = 12 * 1 + 4 = 16

Relative molecular mass of SO2 = 32 + 10 *2 = 64

tSO2/tCH4 = √MSO2/MCH4

t/20 = √64/16 = √4

t/20 = 2

∴ t = 20 * 2 = 40sec

An experiment was conducted to find the mass of one mole of carbon atoms. The results of the experiment showed that a mole of carbon atoms had a mass of 15.78 g. The accepted value of a mole of carbon atoms is 16.00 grams. What is the percent error in this experiment?

Answers

Answer:

1.375%

Explanation:

Percent Error = measured value - accepted value/ accepted value x 100

Measured Value: 15.78

Accepted Value: 16.00

Work:

[tex]\frac{15.78-16.00}{16.00}[/tex] * 100

[tex]\frac{-.22}{16}[/tex] * 100 = -1.375

You cannot have a negative percentage. Therefore the answer is 1.375%

What does the mass of an object depend on?

Answers

Answer:

the mass of an object depends on inertia greater is the inertia greater will be the mass or vice versa

Explanation:

hope it help ^_^

Mass is the most basic property of matter and it is one of the fundamental quantities. Mass is defined as the amount of matter present in a body. The SI unit of mass is the kilogram (kg). The formula of mass can be written as:

Mass = Density × Volume

The mass of a body is constant; it doesn’t change at any time. Only in certain extreme cases when a huge amount of energy is given or taken from a body, the mass may be impacted. For example, in a nuclear reaction, a tiny amount of matter is converted into a huge amount of energy, this reduces the mass of the substance.

There are various units for calculating mass, like, kilograms, grams, lbs, pounds, etc., but the SI unit of mass is "kilograms" or kg. Every unit of mass can be converted to other units by using a proper conversion formula without affecting the meaning and essence of the quantity to be measured.

HENCE,MASS OF AN OBJECT DEPENDS ON:

size of an atom or moleculesAnd number of atoms and molecules of the body.
