Which among the following is the heavist?A. 1 mol of oxygenB. One mole

1.	Which among the following is the heavist?A. 1 mol of oxygenB. One molecule of sulphur trioxideC. 100 amu of uraniumD. 100 mol of hydrogen
Answer» Finding the masses of others `1 mol O_(2) = 32g` 1 molecule `SO_(2) = (64g mol^(-1))/(6.022xx10^(23) "molecules" mol^(-1))` `= 10.62xx10^(-23)g` `= 1.062xx10^(-22)g` 100 amu of uranium `= 100 am u xx (1.66xx10^(-24)g)/(1 am u)` `= 1.66xx10^(-24)g` `10 mol` of hydrogen `= (10 mol) (2g mol^(-1)) = 20g`

Assertion: Laboratory reagents are usually made up to a specific molarity rather than a given molality. Reason: The volume of a liquid is more easily measured than its mass.A. (a)If both assertion and reason are true and the reason is the correct explanation of the assertion.B. (b)If both assertion and reason are true and the reason is not the correct explanation of the assertion.C. (c )If assertion is true but reason is false.D. (d)If assertion is false but reason is true.
Which of the following statements is correct about the reaction given below:- `4Fe(s)+3O_(2)(g)rarr2Fe_(2)O_(3)(g)`A. Total mass of iron and oxygen in reactants = total mass of iron and oxygen in product, therefore, it follows law of conservation of mass.B. Total mass of reactant = total mass of product, therefore, law of multiple proportions is followed.C. Amount of `Fe_2O_3` can be increased by taking any one of the reactants (iron or oxygen ) in axcess.D. Amount of `Fe_2O_3` produced will decreased if the amount of any one of the reactants (iron or oxygen ) is taken in excess.
Assertion: On heating, a solid usually change to a liquid and the liquid on further heating change to the gaseous state. Reason : Arrangement of constituent particles is different in solid, liquid and gaseous state.A. If both assertion and reason are true and reason is the correct explanation of assertionB. If both assertion and reason are true but reason is not correct explanation of assertion.C. If assertion is true but reason is false.D. If both assertion and reason are false.
