To find the total mass of the products, we need to determine the molar mass of sodium chloride (NaCl).
The molar mass of sodium (Na) is 22.99 g/mol, and the molar mass of chlorine (Cl) is 35.45 g/mol.
Since the balanced chemical equation shows that 2 moles of sodium combine with 1 mole of chlorine to form 2 moles of sodium chloride, we can calculate the molar mass of NaCl:
(2 moles Na) x (22.99 g/mol Na) + (1 mole Cl) x (35.45 g/mol Cl) = 58.44 g/mol NaCl
Therefore, the total mass of the products will be 58.44 amu.
To determine the total mass of the products, we need to calculate the molar mass of sodium chloride (NaCl).
The molar mass of sodium (Na) is 22.99 g/mol, and the molar mass of chlorine (Cl) is 35.45 g/mol.
In the chemical equation, we can see that 2 moles of sodium react with 1 mole of chlorine to produce 2 moles of sodium chloride.
So, the molar mass of sodium chloride (NaCl) can be calculated as:
2*(22.99 g/mol) + 35.45 g/mol = 58.44 g/mol
Since the given total mass of the reactants is 58.44 amu (which is equivalent to g/mol), the total mass of the products will also be 58.44 amu.
Therefore, the correct answer is:
58.44 amu
To find the total mass of the products, we can use the balanced chemical equation provided. The coefficients in the equation represent the number of moles of each substance involved in the reaction.
In this case, the coefficients are 2 for Na (sodium) and 1 for Cl2 (chlorine). Using the molar masses, we can calculate the total mass of each reactant:
2Na: 2 moles * molar mass of Na = 2 * 22.99 g/mol = 45.98 g/mol
Cl2: 1 mole * molar mass of Cl2 = 1 * 35.45 g/mol = 35.45 g/mol
Adding these masses together, we get 45.98 g/mol + 35.45 g/mol = 81.43 g/mol for the total mass of the reactants.
According to the law of conservation of mass, the total mass of the reactants should be equal to the total mass of the products. Therefore, the total mass of the products should also be 81.43 g/mol.
