To find the mass of the sample, you can use the formula:
mass = volume × density
Given the density (D) is 1.01 g/mL, we can find the mass of each sample for each trial:
Trial 1: mass = 25.0 mL × 1.01 g/mL = 25.25 g
Trial 2: mass = 20.0 mL × 1.01 g/mL = 20.20 g
Trial 3: mass = 50.0 mL × 1.01 g/mL = 50.50 g
Trial 4: mass = 25.0 mL × 1.01 g/mL = 25.25 g
Trial 5: mass = 20.0 mL × 1.01 g/mL = 20.20 g
Trial 6: mass = 25.0 mL × 1.01 g/mL = 25.25 g
Now, to find the mass of solid per mass of sample (g/g), we will use the formula:
mass of solid/mass of sample = mass of dry solid / mass of sample
For each trial:
Trial 1: (10.767 g) / (25.25 g) = 0.4266
Trial 2: (8.436 g) / (20.20 g) = 0.4178
Trial 3: (21.770 g) / (50.50 g) = 0.4313
Trial 4: (10.826 g) / (25.25 g) = 0.4286
Trial 5: (8.671 g) / (20.20 g) = 0.4293
Trial 6: (10.942 g) / (25.25 g) = 0.4331
So, the mass of solid per mass of sample for each trial is:
Trial 1: 0.4266 g/g
Trial 2: 0.4178 g/g
Trial 3: 0.4313 g/g
Trial 4: 0.4286 g/g
Trial 5: 0.4293 g/g
Trial 6: 0.4331 g/g
