Final answer:
The mass of 50 mL of water is 50 grams.
Step-by-step explanation:
To find the mass of 50 mL of water, we can use the density formula: density = mass/volume. In this case, the density of water is given as 1 g/mL. Rearranging the formula gives us mass = density * volume. Plugging in the values, we get mass = 1 g/mL * 50 mL = 50 grams. Therefore, the mass of 50 mL of water is 50 grams.
