2017年4月10日 · 1 molecule of C3H7O has 7 atoms of hydrogen (remember that the numbers to the right of each symbol ara subscripts and they indicate the number of atoms of that element in the molecular formula). Then 5 molecules will have 5 * 7 atoms of hydrogen. 5 * 7 = 35.

2023年9月5日 · The molecular formula C3H7O represents two isomers: isopropyl alcohol and n-propanol. Explanation: The molecular formula C3H7O represents different isomers of a compound called propanol. There are two isomers of propanol: Isopropyl alcohol: It has the structural formula CH3CH(OH)CH3. It is also known as 2-propanol.

Answer: The answer is "35 atoms". Explanation: The Formula for isopropyl alcohol is: [tex]C_3H_8O[/tex] In 1 molecule of [tex]C_3H_8O[/tex] = 8 atoms of hydrog…

2024年5月25日 · There are a total of 35 hydrogen atoms in 5 molecules of isopropyl alcohol C3H7O. Each molecule contains 8 hydrogen atoms (7 in the three carbon-hydrogen bonds and 1 in the hydroxyl group), so 5 ...

2018年9月29日 · The question asks about the number of hydrogen atoms in 4 molecules of isopropyl alcohol, which has the molecular formula C3H7O. According to the formula, one molecule of isopropyl alcohol contains 7 hydrogen atoms. Therefore, to find the total number of hydrogen atoms in 4 molecules, we multiply 7 atoms by 4, yielding:

2017年11月10日 · The correct answer is d. 35 x (6.02 x 10^23) as the formula C3H7O shows that each molecule of isopropyl alcohol contains 7 hydrogen atoms. Therefore, if you have 5 molecules, you need to multiply 5 by 7 to get the number of hydrogen atoms, hence 35 atoms.

2023年9月29日 · To find out how many carbon atoms are in 57 molecules of C3H7O (which is a compound containing carbon, hydrogen, and oxygen), we can use dimensional analysis. Here's how you can calculate it step by step: Start with the number of molecules: 57 molecules of C3H7O. Determine the number of carbon atoms in one molecule of C3H7O.

2019年11月15日 · The question asks how many hydrogen atoms are in 5 molecules of isopropyl alcohol, C3H8O. The molecular formula for isopropyl alcohol indicates that there are 8 hydrogen atoms per molecule.

2024年1月29日 · For C3H7O combustion, the unbalanced chemical equation would be: C3H7O + O2 → CO2 + H2O. To balance the equation, every carbon atom in C3H7O must result in one molecule of CO2, meaning we need 3 CO2 in the products. We have 7 hydrogen atoms in C3H7O, requiring ½ the number of H2O molecules, which gives us ⅔ × 7 = 3.5 H2O.

2021年4月20日 · Thus, it can be said that there are 7 hydrogen atoms in 1 molecule of isopropyl alcohol, C3H7O profile Answered by Netta00 • 2.8K answers • 19.7M people helped
