Question

in the lab, we found that we obtained 0.90 grams of water vapor (h₂o). according to our calculations, we predicted we would produce was 1.72 g h₂o. what was the % yield?
percent yield = (actual yield / theoretical yield) × 100%
% yield = (□ / □) × 100
% yield = □
possible options: 52.32 %, 0.90, 0.5232%, 1.72, 12.6, 191.11%, 0.191%

Explanation:

Step1: Identify Actual and Theoretical Yields

Actual Yield = 0.90 g (water vapor obtained), Theoretical Yield = 1.72 g (predicted water vapor).

Step2: Plug into Percent Yield Formula

Percent Yield = $\frac{0.90}{1.72} \times 100\%$
Calculate $\frac{0.90}{1.72} \approx 0.5232$, then multiply by 100%: $0.5232\times100\% = 52.32\%$

Answer:

52.32%
