Determine the mass of 2.5 cups of water if the density of water is 1.00 g/cm3 and 1 cup = 240 ml.

Density= Mass/volume Volume of the 1 cup of water is 240 mL, Volume of 2.5 cup of water would be: 240 * 2.5 mL = 600 mL.= 600 cm^3 (Because mL and cm^3 are same units.) We know that density of water is 1g/cm3 and Density = Mass/volume, so putting the values of density and volume of 2.5 cups we would get, 1= Mass of 2.5 cups of water/600mL 1 g/cm^3= Mass/600 cm^3 600 g= Mass. So the mass of the 2.5 cups of water is 600 grams.

Adozen is 12, and your needing to calculate the weight of one medium egg, so i would do 21/12=1.75 per egg, and check your answer by doing 1.75 * 12= 21 : ) : ): ): ): ) i hoped i
