Question

0.46 g of an organic compound gave 0.066 g of water and 0.426 g of carbon dioxide on combustion. calculate the % of C and H . this is 5 mark pls write step by step​

Answer 1

Explanation:

given

organic compound = 0.46g

water present in it = 0.066

carbon dioxide present in it = 0.426g

organic compound = water + carbon dioxide

percentage of C = amount present/ total amount of compound × 100

so, = 0.426/ 0.46 × 100

= 92.60℅ approx 93℅

percentage of H = 0.066/ 0.46 × 100

= 14.34 ℅
