Answer:
Molality = 66.67g/L
Explanation:
Mass of sucrose = 100g
Volume of water = 1.50L
Molality = mass of substance/ volume in L
Molality = 100 / 1.50
Molality = 66.67g/L
Molality of 100g of sucrose in 1.50L of water is 66.67g/L
The sum of protons and neutrons in an atomic nucleus would be the MASS NUMBER.
