Need help with question one and two please located on lab report requirements

Skills Necessary to Accomplish Objectives: - Measuring mass using the mass by difference method. - Proficient use of volumetric flasks, graduated pipets, and volumetric pipets. - Correctly reporting significant figures in measurements and calculations. - Communicating results clearly, using good laboratory technique, and performing experiments with accuracy and precision. In the laboratory: 1. Following the procedure you composed in your pre-lab assignment, prepare 100.00 of a 0.850M NaCl solution using a 100 -mL volumetric flask for volume and a centigra: balance for mass. Record your data in the space that follows. Keep in mind you will eventually calculate both molarity and mass percent of the solution. Collect all necessary data. +49725g of Naci tequred to prefore 100mL of 20.850m NiaC Solution. mass of wergh boat: 2.02g mass of weigh bast with Naci:7.02g 2. Determine the density of the solution using a 10ml volumetric pipet for volume and a centigram balance for mass. Perform two trials. Record your data in the space that follows. Truil 2: mares of 30mL beacer :21.42g 3. Determine the density of the solution using a 10mt graduated pipet for volume and a centigram balance for mass. Perform two triaks. Record the data in the space that follows. For the two trials, using the following procedure: (a) For Trial 1: Fill the graduated pipet exactly to the zero mark and then transfer the entire contents to a beaker. (b) For Trial 2: Fill the graduated pipet to just below the zero mark and then transfer less than 9mt to a beaker. \begin{tabular}{lr} a. maass of 30mL beaker: 21.42g & 32.649 \\ mass of 30mL beaker t solution: 32649 & 24.429 \\ \hline 11.229 \end{tabular} Lab Report Requirements This is an informal report. There is no need for an introduction, safety, procedure, written analysis, or conclusion. For calculations, you must show all work to receive full credit! Handwritten work (calculations only) must be neat; illegible writing will NOT be given the benefit of the doubt. 1. Calculate the molarity of the solution. 2. Calculate the mass percent of the solution. 3. Take another look at the procedure you prepared before lab. It likely wasn't perfect. What did you forget to include in your original draft
