ρ = m ÷ V= 1.25
Note
Simplified model: these results assume ideal behaviour (ideal gases, dilute solutions, complete reactions) and standard textbook constants. Real laboratory values vary with temperature, pressure, purity and activity coefficients. Do not rely on this for safety-critical or analytical work.

How is the density of a solution calculated?+
Density equals mass divided by volume: ρ = m / V, typically expressed in grams per milliliter (g/mL) or kilograms per liter for solutions. It tells you how tightly packed the mass of dissolved solute and solvent is within a given volume.
Why is the density of a solution usually different from that of pure water?+
Dissolved solutes add mass to the solution without adding a proportional amount of volume, so most aqueous solutions are denser than pure water, and the difference grows with concentration. This is why sugar syrup or brine measurably sinks below plain water.
Can I use solution density to estimate concentration?+
Yes — for many common solutions (like saline, sugar syrups, or acids), density correlates closely with concentration, and reference tables or hydrometers let you estimate percent concentration directly from a measured density. This is a common quality-control technique in food and chemical industries.
Does temperature affect solution density?+
Yes, virtually all liquids expand slightly as they warm, which lowers density, so a solution's density should always be reported alongside the temperature it was measured at. Reference density tables are typically given at 20°C or 25°C for this reason.
What's a common unit mistake when calculating solution density?+
Mixing mass units (grams vs. kilograms) with volume units (milliliters vs. liters) without converting consistently will scale your result by a factor of 1000 in either direction. Always confirm your mass is in grams and volume in milliliters if you expect a result in g/mL.
