- Calculating the molar mass of molecules and compounds
- Converting between grams and moles
- Calculating the number of atoms in a given mass of a substance
- Calculating the mass of a substance containing a given number of atoms
- Calculating the number of moles in a given mass of a substance
Overall, the worksheet is a comprehensive assessment of students' understanding of molar mass and its application to real-world problems. Here is a brief description of each of the questions on the worksheet:
Questions 1-8: These questions ask students to calculate the molar mass of molecules and compounds, convert between grams and moles, and calculate the number of atoms in a given mass of a substance.
Questions 9-11: These questions ask students to calculate the mass of a substance containing a given number of atoms, the number of moles in a given mass of a substance, and the mass of a substance needed to form a given number of moles of the substance.
Question 12: This question asks students to calculate the mass of 1 uranium atom.
Questions 13-15: These questions ask students to calculate the moles of sodium hydroxide in a kilogram of caustic soda, the number of hydroxide molecules in a kilogram of sodium hydroxide, and the moles of aspirin formed from 54 g of aspirin.
Questions 16-18: These questions ask students to calculate the mass needed to form 5.8 moles of heptane, the moles of sulfuric acid produced from 0.24 kg of H2SO4, and the moles of H2O formed from 12500 mg of H2O.
Question 19: This question asks students to calculate the number of grams of sodium chloride needed to have 4 moles of this substance.
Question 20: This question asks students to calculate the molar mass of a substance given the mass used and the number of moles.

This lesson contains one activity in the beginning to rise previous knowledge about how organisms are classified. Afterwards, concepts like Taxonomy, Biodiversity and Classification are defined in order to understand how they are classified and the objective if this. The structure of Scientific Names is presented with some examples. Then, the classification is explained (Domain, Kingdom, Phylum, etc.) with the human example. Finally, a closure activity is presented in order to evaluate which taxonomies are more related in order to compare the criteria.

1. Begin by reading a text containing information about human fossils.
2. Observe images of human fossils and match each image with the appropriate description, providing justifications for their choices.
3. Proceed to construct a timeline that illustrates the evolution of humanity, with a specific focus on understanding the reasons for this evolution and its significance.
4. Answer open questions in order to understand the evolution of the human being, specifically why it happened and the importance of it.
In essence, this worksheet serves as a comprehensive exercise to help students explore the evolution of human beings by integrating textual and visual information, critically analysing it, and drawing connections to broader concepts.
