Bismuth 210 has half life of 5 days and a sample originally has a mass of 800mg What is the formula for mass remaining after t days?
The mass can be determined with the formula m=800(.5)^(t/5)
An empty beaker has a mass of 115 g After some water is added to the beaker the mass is 147 g What is the mass of the water?
32 g
What if your math book has the mass of about one?
Mass of about one is completely meaningless. You need to provide units to give that number meaning. Regardless of that, I don't understand your question. Who cares what the mass of your text book is?
Ten uses of integration in calculus?
Integration can be used whenever you have to multiply two numbers, one of which varies - for example, to calculate an area, you calculate height times width, but the height may vary in certain geometric figures.Integration can also be used to calculate:Work = force times distance (force may not be constant). Center of mass - you need to take the average of many pieces of massMoment of inertiaArea of a surfaceVolumesAnd many others more.Integration can be used whenever you have to multiply two numbers, one of which varies - for example, to calculate an area, you calculate height times width, but the height may vary in certain geometric figures.

One kg is equal to one?
No, it is not. One kg is a measure of mass while one (by itself) is a pure number - and that is a concept and has no mass at all.
