a student in chm 11500 lab measured the mass of a 250-ml erlenmeyer flask and recorded it as 79.83 g. she added 10.00 ml of deionized water from a 25-ml buret to the flask. the mass of the flask plus the water was 89.82 g. the temperature of the water was 22 °c. what is the calculated volume of the water that the student measured?

The human activities in two locations are described below: location a: rampant use of plastic containers location b: excessive use of pesticides and fertilizers which statement is most likely true? location a will have poor air quality because plastic is biodegradable. location a will experience water scarcity because plastic absorbs moisture. the population of honeybees will increase in location b because production of crops will increase. the population of fish in location b will decrease because the water is contaminated.

Calculate the mass of 0.750 mol of the following substance. na3po4. , i'm not quite sure on how to set up the problem to solve! : (

In in , is to a 28.4-g (1-oz)−23.0 °c to −1.0 °c?
