What masses of salt and water will be required to prepare 500 g of its 15% solution?
September 5, 2021 | education
| Given: m (salt solution) – 500 g
ω (salt solution) – 15%
find: m (salt), m (water)
ω = m (salt) / m (salt solution) * 100%
15% = x / 500 * 100%
X = 15 * 500/100
X = 75 g
m (salt) = 75 g
m (water) = 500 g – 75 g = 425 g
Answer: m (salt) = 75 g
m (water) = 425 g
