A student has a 1g sample of each of the following compounds: NaCl, KBr, and KCL Which of the following lists the samples in order of increasing number of moles in the sample?

The increasing order of the moles in sample has been, KBr < KCl < NaCl.

The moles of sample have been defined as the mass of sample with respect to  molar mass. The moles of sample have been given by:

The molecular mass of the sample has been given by mwt.

The moles in 1 g mass of the following samples has been given by:

1 gram sample of NaCl has been 0.017  mol.

1 gram sample of KBr has been 0.008 mol.

1 gram sample of KCl has been 0.0.13 mol.

The increasing order of the moles in sample has been, KBr < KCl < NaCl.

Given :

A student has a 1 g sample of each of the following compounds: NaCl, KBr, and KCl.

To Find :

The samples in order of increasing number of moles in the sample.

Solution :

Molecular mass of NaCl, KBr, and KCl is 58.5 g/mol , 119 g/mol and

74.5 g/mol respectively .

Moles of NaCl , .

Moles of KBr , .

Moles of KCl , .

The order of moles in increasing order is :

KBr , KCl and NaCl .

Hence , this is the required solution .

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
