Sodium reacts with chlorine to form the compound sodium chloride, or salt. The chemical formula below shows how the two elements combine into a compound.

Question

2Na + GIz -> 2NaCI
If the total mass of the reactants is 58.44 amu, what will be the total mass of the products?
(1 point)
a 60 amu
b 58.44 amu
c 116.88 amu
d 29.22amu

Answer 1

The chemical formula shows that 2 moles of sodium (Na) react with 1 mole of chlorine (Cl) to form 2 moles of sodium chloride (NaCl).

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.

Therefore, the molar mass of sodium chloride (NaCl) is:
2 (molar mass of Na) + 1 (molar mass of Cl) = (2)(22.99) + 35.45 = 45.98 + 35.45 = 81.43 g/mol.

Since the total mass of the reactants is given as 58.44 amu, and the molar mass of the products is 81.43 g/mol, we can determine the total mass of the products using the following calculation:

(total mass of reactants) x (molar mass of products) / (molar mass of reactants)
= 58.44 amu x (81.43 g/mol) / (58.44 g/mol)
= 81.43 amu

Therefore, the total mass of the products will be 81.43 amu.

The correct answer is: a) 81.43 amu.

Answer 2

that is not right
