Molarity is defined as the number of moles of solute in 1 L of solution the mass of Ca(NO₃)₂ present - 8.50 g therefore number of moles of Ca(NO₃)₂ - 8.50 g / 164 g/mol = 0.0518 mol the volume of solution prepared is 755 mL therefore if there are 0.0518 mol in 755 mL then in 1000 mL the number of moles - 0.0518 mol / 0.755 L molarity is therefore - 0.0686 M
The turbine since the definition of this word is <span> a machine for producing continuous power in which a wheel or rotor, typically fitted with vanes, is made to revolve by a fast-moving flow of water, steam, gas, air, or other fluid. </span>
