The molar mass of Sb2S3 is approximately equal to 339.7 g/mol. We calculate the number of moles of Sb2S3 by dividing the given mass by the molar mass.
n = 23.5 g / (339.7 g/mol)
n = 0.0692 mols
To calculate for the number of formula units, we multiply the number of mols by the Avogadro's number,
number of formula units = (0.0692 mols)(6.022 x 10^3)
= 4.167 x 10^22 formula units
c)pattern
Explanation:
A general change such as increasing or decreasing numbers is called a pattern. A pattern shows a structured way of implementing a change.
- Patterns can be a form of increment in values by adding a particular number at intervals.
- It can be a division, multiplication or subtraction of a consistent number.
- Patterns can provide insight into understanding a number system or a group of numbers.
- Sequences are usually derived from patterns.
