please help me on all three.

1. instead if pipetting water, you are pipetting a 2M NaCl solution. the densiry of a 2M NaCl solution is 1.077 g/mL. if toy were to pipette 5 mL of this solution onto a scale, how mant grams would tou expect this to weigh? Round ro the nearest 2 decimal places.

2. you use a serological pipet to place 53 mL of 2M NaCl on a scale. the mass of the solution is found to be 67.37 g, but based on the density you know the solution should have a mass of 57.08 g. what is the percent error?

3. you want ro makw a 3.5 M soultion of compoin X. The molecular weight of compound X is 260.07 g/mol. how many grams of compound X do you need ro weight out to make 250 mL of this solution? round to nearest 2 decimals.
