I have 2 questions:

Assuming that water has a density of exactly 1 g/cm3, find the mass of one cubic meter of water in kilograms.

Suppose that it takes 10.0 h to drain a container of 5700m3 of water. What is the "mass flow rate," in kilograms per second, of water from the container.

Thanks!!

• physics -

for the first question,

there is 1g of water per 1 cm cube

therefore there is 1000 kg of water per 1 m cube

for the 2nd one, im not sure
