No, there will be more molecules in the 50 grams of NaCl, because its molacular weight is lower.
NaCl has a molaculair mass of 58.44 g/mol and MgCl2 has a molcular mass of 95.21 g/mol.
50 g / 58.44 g/mol = 0.86 mol NaCl
50 g / 95.21 g/mol = 0.53 mol MgCl2
The avogadro contstant states that 1 mole equals 6.02214179*1023 molecules.
So you have 0.86 * 6.022*1023 = 5.18*1023 molecules of NaCl and
0.53 * 6.022*1023 = 3.19*1023 molecules of MgCl2.

How many pounds are found in 25.29 grams of NaCl?
A pound (weight) is equivalent to 453.59 grams. Therefore, 25.29 grams is the same as 0.056 pounds.
Is 1 mole of Na Cl and 1 mole of MgCl2 has same No of ions?
NO!!! In one molecule of NaCl there are TWO(2) ions ; Na^(+) & Cl^(-) In one molecule of MgCl2 there are THREE(3) ions ; Mg^(2+) , Cl^(-) & Cl^(-) . Hence it follows that in one mole of NaCl there are less ions than there are in one mole of MgCl2, by a ratio of 2:3 .
What has a greater boiling point elevation when dissolved at a concentration of 1mol in water with NaCl or MgCl2?
In the same volume of water, one mole of MgCl2 will give rise to a greater boiling point elevation. This is explained by the fact that boiling point elevation is a colligative property, that is, the relative amounts of the constituents are important and not their identity. We can determine by inspection that, upon dissociation, more ions will be produced by MgCl2 than NaCl since there are more atoms in the MgCl2 molecule. So, for one mole of MgCl2, we will produce one mole of magnesium and two of chlorine (three total). For one mole of NaCl, we produce one mole each of potassium and chlorine. By employing the principle stated above, we can come to the correct conclusion.
You apply the same amount of heat to five grams of substance a and five grams of substance b the temperature of both substances increase by the same amount what can you conclude?
You can conclude that both substances have the same specific heat capacity. This means that they require the same amount of energy to change their temperature by a certain amount.
Does 100 grams of something have the same density as 200 grams of the same matter?
Yes, density is an intrinsic property of a material and remains constant regardless of the amount of the substance. So 100 grams of a substance will have the same density as 200 grams of the same substance.
How many grams are in half a mole of NaCl?
By definition, one mole would be the same as the atomic mass or molecular mass. You take the number of moles and multiply it by the molecular mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the molecular mass. The molecular mass is the atomic masses of the elements in the compound added together.Na- 23.0Cl- 35.5NaCl- 58.5 grams in one mole
Is 0.9 NaCl and NaCl the same?
NaCl is the formula unit of sodium chloride; 0,9 NaCl is a solution, probable o,9 molar.
What is the mass of 33.93 grams?
The mass of 33.93 grams is simply 33.93 grams. It is a measure of the amount of matter in an object and is expressed in grams, which is a unit of mass in the metric system. Therefore, the mass remains the same at 33.93 grams.
How many grams of sodium chloride is obtained by the action of chlorine with 4 moles sodium?
A mole of an element or compound is 6.022 x 1023 (Avogadro's constant) molecules of that substance. This number is the number of molecules it takes for an amount of substance to have a mass in grams the same as its molecular mass: carbon has a molecular mass of 12, so 6.022 x 1023 (one mole) carbon atoms have a mass of 12 grams. The molecular mass of sodium is 23 (22.989) so one mole of sodium has a mass of 23 grams. Sodium chloride has a molecular mass of 58.44 so a mole of NaCl is 58.44 grams. One mole of sodium will make one mole of sodium chloride. Na + Cl => NaCl So four moles of sodium will make four moles of sodium chloride. 4Na + 4Cl => 4NaCl Four moles of NaCl has a mass of 4 x 58.44 = 233.76 grams.
Is SiCl plus Mg---MgCl2 plus Si Balanced?
The chemical equation SiCl + Mg → MgCl2 + Si is not balanced. To balance it, you would need to adjust the coefficients to ensure that the number of atoms of each element is the same on both sides of the equation.
What is the correct name for the salt in sea water?
The primary salt in the oceans is sodium chloride, the same as ordinary table salt. Seawater also contains salts of calcium, magnesium, and potassium in varying amounts, both as chlorides and sulfates.
How many moles of NaCl would form from 3.25 moles of NaHCO3?
To find the moles of NaCl formed from NaHCO3, we need to consider the stoichiometry of the reaction. The balanced equation is: 2 NaHCO3 -> Na2CO3 + H2O + CO2 Therefore, for every 2 moles of NaHCO3, we get 1 mole of NaCl. Therefore, 3.25 moles of NaHCO3 would produce 1.625 moles of NaCl.
