The density of water at 400C is 0.992 g/mL What is the volume of 27.0 g of water at this temperature?
pantera1 [17]

Answer:

Volume of water at this temperature is 27.2 mL

Explanation:

We know that density=\frac{mass}{volume}

Here density of water is 0.992 g/mL

Here mass of water is 27.0 g

So volume=\frac{mass}{density}

                         = \frac{27.0g}{0.992g/mL}

                         = 27.2 mL
