Calculating the Mass of Sodium Needed to React with Chloride

Given the following equation, Na+ + Cl → NaCl, how many grams of sodium would need to react with 4.5 moles of chloride?

The right response is B. 103.5 g. The mole ratio of sodium to chloride is 1:1 according to the equation Na+ + Cl → NaCl. Since 4.5 moles of chloride are provided, the equation requires 4.5 moles of sodium to be balanced. We must utilize the molar mass of sodium, which is 22.99 g/mol, to get the mass of sodium.

We obtain 103.5 g of sodium by multiplying 4.5 moles of sodium by 22.99 g/mol. The correct response is B. 103.5 g.

The equation requires 1 mole of sodium for every mole of chloride, giving 4.5 moles of sodium and 103.5 g.

Given the equation Na+ + Cl → NaCl, how many grams of sodium would need to react with 4.5 moles of chloride?
A. 15.6 g
B. 103.5 g
C. 5.1 g
D. 157.55 g
E. 53.5 g The correct answer is B. 103.5 g. The equation requires 4.5 moles of sodium to react with 4.5 moles of chloride based on the 1:1 mole ratio between sodium and chloride.
