WebSulfur is essential to all living things. It is taken up as sulfate from the soil (or seawater) by plants and algae. It is used to make two of the essential amino acids needed to make proteins. It is also needed in some co-enzymes. The average human contains 140 grams and takes in about 1 gram a day, mainly in proteins. WebWhich one of the following contains the most moles of oxygen atoms?

How many sulfur atoms are in a mole of sulfur? – Wise-Answer
Web15 aug. 2024 · The oxidation state of the sulfur is +6 (work it out!); therefore, the ion is more properly named the sulfate (VI) ion. The sulfite ion is SO 32-. The oxidation state of the sulfur is +4. This ion is more properly named the sulfate (IV) ion. The -ate ending indicates that the sulfur is in a negative ion. WebTo calculate number of molecules, we have: Number of Molecules = Number of Moles ∗ Avogadro ′ sNumber Number of Molecules = 34.99 ∗ 6.02 ∗ 1023 Number of Molecules = 2.1063 ∗ 1024 Now we have to perform moles to grams calculation: Molar Mass = 107.868 (for calculations, tap Molar Mass Calculator) By using moles to grams formula: m = n ∗ M gemtesa dry mouth
