23

gram sodyum elementi

Write Equation: Write the conservation of mass equation. $\newline$ Total mass of reactants = Total mass of products. $\newline$ $23$ grams (sodium) + $m$ grams (water) = $40$ grams (caustic) + $1$ gram (hydrogen).
Solve for m: Solve for m. $\newline$ $23 + m = 40 + 1$ , $\newline$ $23 + m = 41$ , $\newline$ $m = 41 - 23$ , $\newline$ $m = 18$ .
