molarity of a solution means mols per liter.
First, you need to convert 23 grams on NaCl into mols. 23g divided by molar mass (58.44g/mol) which gives you .394 mols.
Now, you need to convert 500ml to L which moves the decimal three places to the left, giving you .500L of solution.
Finally, divide the mols over solution to get .787M
To find the molarity, we first need to calculate the number of moles of NaOH. The molar mass of NaOH is 40 g/mol (sodium=23g/mol, oxygen=16g/mol, hydrogen=1g/mol). Thus, 80g NaOH is 2 moles (80g / 40g/mol). Given 1L of solution, the molarity is 2 moles / 1 L = 2 M.
The gram formula mass of sodium (Na) is approximately 23 grams per mole.
1 mole of sodium weights 23g 1 mole of sodium = 6.02 x 10^23 atoms = 23g 117 atoms = ? 117 x 23 / 6.02 x 10^23 (should be a very small number)
To determine the number of moles in 4g of sodium hydroxide (NaOH), divide the mass by the molar mass of NaOH. The molar mass of NaOH is approximately 40g/mol (Na = 23g/mol, O = 16g/mol, H = 1g/mol). Therefore, 4g of NaOH is equal to 0.1 moles.
First construct a a balanced equation for the reaction : 2Na + 2H2O --> 2NaOH + H2 From the equation, we know that the ratio of Sodium(Na) to the ratio of Sodium Hydroxide(NaOH) is the same. Ar of Na = 23g/mol Number of moles = mass / Ar = 46g / 23g/mol = 2mol (moles of Na used) Since ratio of Na to NaOH is the same, therefore there are also 2 moles of NaOH formed.
Given: 0.5 g NaCl; 0.05 L of solution.1) Find the molar mass of NaCl.(22.99) + (35.45) = 58.44 g/mol of NaCl2) Convert grams of NaCl to moles of NaCl.(0.5 g NaCl) X (1 mol NaCl / 58.44 g NaCl) = 0.00855578 mol NaCl3) Use the molarity equation, M = mol / L, to solve for molarity (M).(0.00855578 mol NaCl / 0.05 L) = 0.17 M
To find the molarity, we first need to calculate the number of moles of NaOH. The molar mass of NaOH is 40 g/mol (sodium=23g/mol, oxygen=16g/mol, hydrogen=1g/mol). Thus, 80g NaOH is 2 moles (80g / 40g/mol). Given 1L of solution, the molarity is 2 moles / 1 L = 2 M.
The Titan 23G was first launched on the 25th of January 1994.
To find the number of atoms in 23g of sodium, divide the mass of the sample by the molar mass of sodium (23g/mol). This gives you the number of moles, which you can then convert to atoms using Avogadro's number (6.022 x 10^23 atoms/mol). So, there are approximately 6.022 x 10^23 atoms in 23g of sodium.
The mass number of NaCl cannot be determined because there are two different elements involved: sodium (Na) and chlorine (Cl). Each element has its own unique mass number based on the sum of protons and neutrons in its nucleus.
The molar ratio of Na to O2 in the reaction 2Na + O2 -> 2Na2O is 2:1. This means that for 23g of Na, we need half as many grams of O2, which is calculated as 23g * (1/2) = 11.5g of O2.
2.3oz = 65.204g
23 grams is equal to 0.023 kilograms.
38g. It used to be 23g.
Atomic mass of NH3 is 17.So there are 1.353mol.
