Answer: The volume of liquid used will be 18.055 mL.
Explanation:
To calculate the volume of liquid, we use the equation for density which is:
We are given:
Mass of the liquid = 26 g
Density of the liquid = 1.44 g/mL
Volume of the liquid = ? mL
Putting values in above equation, we get:
Hence, the volume of liquid used will be 18.055 mL.
9.00 g of H2O
88.0 g of CO2
1.70 g of NH3
