To find the volume in milliliters (ml) from a mass in grams (g) using the density, we can use the formula:
Volume (ml) = Mass (g) / Density (g/ml)
In this case, the mass is 0.777 g and the density of ethyl acetate is 0.902 g/ml. Plugging the values into the formula gives us:
Volume (ml) = 0.777 g / 0.902 g/ml
When we perform the division:
Volume (ml) ≈ 0.861 ml
This means that 0.777 g of ethyl acetate is approximately 0.861 ml. Understanding how to convert between mass and volume is important in many chemical applications, especially when working with liquids, as it helps in accurately measuring and mixing substances for various experiments or recipes.
