Snezhnost [94]3 years ago
4 0

Answer:

4.54 % NaOH

Explanation:

\text{Mass percent} = \dfrac{\text{Mass of component}}{\text{Total mass}} \times 100 \, \%

Data:

Mass  of NaOH     =   11.6 g

Mass of water      =   38.4 g

Mass of solution = 250.0 g

Calculation:

\text{Mass \% NaOH} = \dfrac{\text{11.6 g NaOH}}{\text{250 g solution}} \times 100 \% = \textbf{4.54 \% NaOH}

Elena L [17]

Answer:

1.60x10⁶ billions of g of CO₂

Explanation:

Let's calculate the production of CO₂ by a single human in a day. The molar mass of glucose is 180.156 g/mol and CO₂ is 44.01 g/mol. By the stoichiometry of the reaction:

1 mol of C₆H₁₂O₆ -------------------------- 6 moles of CO₂

Transforming for mass multiplying the number of moles by the molar mass:

180.156 g of C₆H₁₂O₆ ----------------- 264.06 g of CO₂

4.59x10² g ---------------- x

By a simple direct three rule:

180.156x = 121203.54

x = 672.77 g of CO₂ per day per human

So, in a year, 6.50 billion of human produce:

672.77 * 365 * 6.50 billion = 1.60x10⁶ billions of g of CO₂
