Answer:
Explanation:
A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample.
Answer:
Mass of sodium hydroxide needed = 28.2 g
Explanation:
Given data:
Mass of sodium hydroxide = 80 g
Mass of sodium sulfate produced = 142 g
Mass of sodium hydroxide needed = ?
Mass of sodium sulfate produced = 50 g
Solution:
Mass of sodium sulfate produced / Mass of sodium hydroxide = Mass of sodium sulfate produced / x
142 g/ 80 g = 50 g / x
x = 50 g × 80 g / 142 g
x =4000 g/ 142
x = 28.2 g
