consider again the reaction for photosynthesis: 6co₂ + 6h₂o → c₆h₁₂o₆ + 6o₂. what mass of water is required to react completely with 157.35 g co₂? (molar mass of h₂o = 18.02 g/mol; molar mass of co₂ = 44.01 g/mol). 157.35 g co₂ = g h₂o

consider again the reaction for photosynthesis: 6co₂ + 6h₂o → c₆h₁₂o₆ + 6o₂. what mass of water is required to react completely with 157.35 g co₂? (molar mass of h₂o = 18.02 g/mol; molar mass of co₂ = 44.01 g/mol). 157.35 g co₂ = g h₂o

Answer

Answer:

62.77

Explanation:

Step1: Calculate moles of CO₂

$n_{CO_2}=\frac{m_{CO_2}}{M_{CO_2}}=\frac{157.35\ g}{44.01\ g/mol}=3.575\ mol$

Step2: Determine mole - ratio

From the balanced equation $6CO_2 + 6H_2O\rightarrow C_6H_{12}O_6+6O_2$, the mole - ratio of $CO_2$ to $H_2O$ is 1:1. So, $n_{H_2O}=n_{CO_2}=3.575\ mol$

Step3: Calculate mass of H₂O

$m_{H_2O}=n_{H_2O}\times M_{H_2O}=3.575\ mol\times18.02\ g/mol = 62.77\ g$
