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>

Calculate the percentage by mass of oxygen in Al2(SO4)3 (Al=27, S=32,O= 16) PLEASE SHOW FULL WORKING​
White raven [17]

Answer:

There is 61.538% oxygen in Al2(SO4)3.

Explanation:

Wt Of oxygen in the compound = 12*16 = 192 amu.

Total Wt. Of the compound = 2*12+3*32+12*16 = 312 amu.

Thus, percent of oxygen = Wt of oxygen/total Wt. Of compound *100

= 192/312 * 100=61.538 %
