5. Liquid Volume When the metric system was created, they decided that 1 cm 3 of water would equal 1 milliliter of water and the 1 mL of water will have a mass of one gram. 1cm 3 water =1 ml of water = 1 gram copyright cmassengale

6. Water Mass and Volume 1 cm 3 water = 1 mL of water = 1 gram So what would be the mass of 50 mL of water be? 50 grams So what would be the mass of 1 liter of water be? 1 L = 1000 mL so its mass would be 1000 grams or a kilogram. copyright cmassengale
