When 6.13 g of a certain molecular compound X are dissolved in 90. g of formamide (NH2COH), the freezing point of the solution i
belka [17]

Answer:

321.6 g/Mol

Explanation:

mass of solvent in kilograms = 90g/1000 = 0.09 Kg

Given that;

ΔTf = Kf . m . i

Where;

Kf = freezing point constant = 4.25 °C/Kg mol

m = molality of the solution

i = Van't Hoff factor = 1 (since the substance is molecular)

ΔTf = freezing point of pure solvent - freezing point of solution

freezing point of pure solvent = 3 °C

ΔTf = 3 °C - 2.1 °C

ΔTf = 0.9  °C

0.9= 4.25 * 6.13/M/0.09 * 1

0.9= 26.0525/M * 1/0.09

0.9 = 26.0525/0.09 M

0.9 * 0.09M = 26.0525

M = 26.0525/0.9 * 0.09

M= 321.6 g/Mol

John Dalton believed which of the following about atoms?
Snowcat [4.5K]

Answer : Option B) All atoms of a single substance are identical.


Explanation : The scientist John Dalton proposed the atomic theory which had the postulates as follows.


i) All matter/substances consists of indivisible particles known as atoms.

ii) Atoms of the same element/substance are similar in mass,shape and size, but differ from the atoms of other elements.

iii) Atoms obey the law of conservation of energy which says atoms cannot be created or destroyed.

iv) Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form any compound atoms.

v) Atoms of same element can combine in ratio with more than one to form two or more compounds.

vi) The atom is considered to be the smallest unit of matter that can take part in a chemical reaction
