Answer:
What do you need help with
Explanation:
The answer will depend on the number of significant figures you want in your answer, so I can't give you a solid answer, but the process is still the same: you convert from grams to moles by using the molar mass.
You can calculate the molar mass of carbon tetrafluoride from the periodic table, by adding the molar mass of 1 atom of C and 4 atoms of F. Round the total molar mass to the appropriate number and multiply 169 moles by the molar mass you just calculated.
Hope this helps!
The volume of the textbook calculated by the student written to 3 significant figures is 992cm³
- According to this question, a student calculates the volume of his textbook and arrived at an answer of 991.880 cm³.
- To round up this digit to 3 significant figures, which means that only 3 significant numbers should appear in the answer.
- To do this, the number after the third number is 8, which means we can round up the value of 1 to 2. Hence, the volume of the textbook calculated by the student is 992cm³ in 3 s.f.
