what is the mass (by difference) of a sample if the initial mass of the sample in the bottle was 29.89-g and the final mass of the bottle and sample was 22.01-g ?
To calculate the mass of the sample by difference, you need to subtract the final mass of the bottle and sample from the initial mass of the sample in the bottle.
1. Start by writing down the given information:
- Initial mass of the sample in the bottle = 29.89 g
- Final mass of the bottle and sample = 22.01 g
2. Subtract the final mass from the initial mass:
Mass of the sample by difference = Initial mass - Final mass
Mass of the sample by difference = 29.89 g - 22.01 g
3. Perform the subtraction:
Mass of the sample by difference = 7.88 g
Therefore, the mass of the sample (by difference) is 7.88 grams.
