The formula C₃H₇COO⁻Na⁺ represents the **compound **sodium propionate. To calculate the molar mass (Mr) of sodium propionate, we need to add up the individual atomic masses of its constituent elements. Given that Na has a mass of 23 g/mol, C has a mass of 12 g/mol, and O has a mass of 16 g/mol, we can calculate the molar mass as follows:

Here are the molar masses (Ar) of each element provided: Na = 23 C = 12 O = 16 Now let's break down the compound into its elements and their quantities: 1 Na atom: 1 x 23 = 23 3 C atoms: 3 x 12 = 36 7 H atoms: 7 x 1 = 7 (Ar of H = 1) 2 O atoms: 2 x 16 = 32 Next, add up the molar masses of all the elements in the compound: 23 (Na) + 36 (C) + 7 ...

Protons: 11 - Neutrons: 12 - Electrons: 11. By analyzing the atomic number, mass number, and net charge, we can determine the number of protons, neutrons, and electrons in the sodium-23 atom. The sodium-23 atom (Na-23) has a net charge of +1, which means it has one more proton than electrons. To determine the number of protons, neutrons, and ...

A sodium-23 (Na-23) atom has 11 protons, 12 neutrons, and 10 electrons. The +1 charge indicates that it has lost one electron compared to a neutral sodium atom. The number of protons helps determine the elements and is equal to the atomic number, while the number of neutrons is found by subtracting the atomic number from the atomic mass.

2024年10月23日 · The atomic mass of Sodium (Na) is 23. The atomic mass of Oxygen (O) is 16. The atomic mass of Hydrogen (H) is 1. Add the Atomic Masses Together: The formula for the relative formula mass of NaOH is given by: M r = A r (N a) + A r (O) + A r (H) Plugging in the values: M r = 23 + 16 + 1; Calculate the Total: Performing the addition gives: M r ...

A sodium-23 (Na-23) atom with a net charge of +1 has 11 protons, 12 neutrons, and 10 electrons. This conclusion comes from the atomic number identifying the number of protons, the mass number determining the neutrons, and the charge indicating the loss of one electron.

2023年10月9日 · The atomic masses of Na, O, and H are 23, 16, and 1, respectively. Therefore, one mole of NaOH will have a mass of: 23 + 16 + 1 = 40 grams. Learn more about molar mass here:

2023年9月3日 · The atomic mass of an element, such as sodium, is determined based on the weighted average of all its naturally occurring isotopes. For sodium, the naturally occurring isotope is Na-23, which has a mass of 22.98 amu. Since Na-23 is the only naturally occurring isotope of sodium, its atomic mass is essentially the same as its isotopic mass, 22. ...

2024年6月23日 · Sodium (Na): 1 atom, so its contribution is 1 × 23 = 23; Nitrogen (N): 1 atom, so its contribution is 1 × 14 = 14; Oxygen (O): 3 atoms, so their combined contribution is 3 × 16 = 48; Now, we sum these contributions to find the total molecular mass: Molecular Mass of NaNO₃ = 23 + 14 + 48 = 85. Step 3: Calculate the percentage by mass of ...

2020年7月28日 · The mass number for sodium-23 is 23. Given that sodium has 12 neutrons as stated, we can use the formula: A = Z + N where A is the mass number, Z is the atomic number, and N is the number of neutrons. Now, substituting the values we have: 23 = Z + 12 This simplifies to: Z = 23 - 12 Z = 11 This means that the atomic number of sodium (Na) is 11.
