Question

If the % composition of a 'x' component is 35%, find the mass of the dried 'x' component in 100g? mixture + beaker = 50 g, mass of beaker = 23 g

• A. 15.5 g
• B. 9.45 g
• C. 35.5 g
• D. 13.4 g

Answer 1

The correct option is B 9.45 g

mass of beaker $=23g$
mass of mix + beaker$=50g$
mass of mixture $=50-23=27g$
$\%$ composition of mixture $=35\%$
Mass of the x component $=35\times \frac{27}{100}=9.45g$
