Sulfur has an atomic mass of 32 u and Avogadro's number is 6 × 1023 formula units/mole. The number of sulfur atoms in 1 g of sul

Vikki [24]

Answer:

The number of sulfur atoms in 1 g of sulfur is:- $1.875\times 10^{22}$ atoms

Explanation:

Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by $N_0$ .

Avogadro constant:-

$N_a=6\times 10^{23}$

Given atomic mass of sulfur = 32 u

Which means that:-

32 g of sulfur contains $6\times 10^{23}$ of atoms

Also,

1 g of sulfur contains $\frac {6\times 10^{23}}{32}$ of atoms

<u>So, The number of sulfur atoms in 1 g of sulfur is:- $1.875\times 10^{22}$ atoms</u>

An ionic compound has a slightly negative heat of solution in water. would you expect it to be soluble or insoluble in water?

Grace [21]

The ionic compound will be soluble in water.
The value of the heat of solution of a substance is one of the factors that determine whether a substance will dissolve or not. A negative heat of solution signifies that the reaction will be spontaneous, so the ionic compound will dissolve in water.
