Solved the first two problems, post multiple question to get the remaining answer as per Chegg guidelines
Q1)
Need to find Drug A equivalent to 0.75 NaCl
1g of Drug A contains 0.422g of NaCl
Amount of Drug A containing 0.75g NaCl = 1/0.422g * 0.75g = 1.77725
Since we need to give the answer in three significant digits, hence the answer must be 1.78g
Q2)
0.86 w/v% implies 0.86 grams of solute is present in 100ml of solution
1 L = 1000 mL
Hence the answer in g/L will be g/100mL * 1000mL/1L = 10 * 0.86 = 8.6 g/L
