Can you help me with question 1?
**Educational Exercise on NaOH Solutions** **Q1:** Calculate how many moles of NaOH are in 50.0 mL of a 6.82 M NaOH solution. - **Molar mass NaOH = 40.0 g/mol** - **Density NaOH = 1.50 g/mL** **Q2:** Lisa is given a container which only contains 28.021 g NaOH pellets and is tasked with making a 1.12 M NaOH solution. Help Lisa calculate the volume for this 1.12 M NaOH solution. - **Molar mass NaOH = 40.0 g/mol** - **Density NaOH = 1.08 g/mL** **Q3:** Lisa is given a beaker containing 50.0 mL of 0.816 M NaOH solution. The density of this 0.816 M NaOH solution is 1.08 g/mL. Help Lisa calculate the percent by mass and the percent mass/volume of NaOH in the solution. - **Molar mass NaOH = 40.0 g/mol**
