In the above reaction, 5g of toluene is converted into benzaldehyde with 92 % yield. The amount of benzaldehyde

In the above reaction, 5g5g of toluene is converted into benzaldehyde with 9292 % yield. The amount of benzaldehyde produced is____ ×10−2g× {10}^{- 2}g

Correct answer

0

Step-by-step solution

In the above reaction, 5g of toluene is converted into benzaldehyde with 92 % yield. The amount of benzaldehyde

Molar mass of benzaldehyde=106g/mol106g / mol

Number of moles of toluene =592= \dfrac{5}{92}

Number of moles of Benzaldehyde =0.92×592= 0 . 92 \times \dfrac{5}{92}

Mass of Benzaldehyde =0.92×592×106=5.30g=530×10−2g= 0 . 92 \times \dfrac{5}{92} \times 106 = 5 . 30g = 530 \times {10}^{- 2}g
