Suppose we want to charge a flask with 4.0 g of sugar. We put the empty flask on a balance and it is determined to weigh 190 g. Enter the weight we would expect to see on the balance when we're done adding the sugar.

To find the expected weight on the balance after adding the sugar, we need to consider the mass of the flask and the mass of the sugar.
First, we know that the flask weighs 190 g when empty. Let's denote this as the initial weight of the flask (W_initial).
Next, we need to calculate the mass of the sugar that will be added to the flask, which is given as 4.0 g.
Now, we can calculate the expected weight on the balance after adding the sugar.
The weight of an object is the sum of its mass and the gravitational force acting on it. In other words, weight = mass × gravity.
However, since we are dealing with relatively small quantities of sugar, we can assume that the gravitational force is constant. So, we can substitute weight with mass in this case.
Now, let's denote the expected weight on the balance after adding the sugar as W_final.
We can calculate W_final by adding the mass of the flask (W_initial) to the mass of the sugar.
W_final = W_initial + mass of sugar
W_final = 190 g + 4.0 g
W_final = 194.0 g
Therefore, the expected weight we would see on the balance after adding the sugar is 194.0 g.
