what is mass
A ruler is used to measure length or distance, while a balance is used to measure weight or mass.
The weight of a ruler in newtons would depend on its mass and the acceleration due to gravity. Typically, a standard ruler would have a very small mass, so its weight in newtons would be very minimal, likely less than 1 newton.
To determine the density of a block, you can use a balance to measure its mass and a ruler to measure its dimensions. The density of the block can then be calculated by dividing the mass by the volume.
To find the density of a rectangular solid with just a ruler, you would need to measure the length, width, and height with the ruler. Then, calculate the volume by multiplying the three measurements together. Finally, divide the mass of the rectangular solid by the volume to find the density.
The density of a substance is the ratio of its mass to its volume. So, I would measure the mass and volume of a substance to calculate density.
A standard ruler is 12 inches or 1 foot
To find the center of mass of a meter ruler, you can use the balancing method. Simply support the ruler horizontally at various points along its length until you find a point where it balances perfectly; this point is the center of mass. Alternatively, if the ruler is uniform, the center of mass can be calculated at the midpoint, which is at 50 cm.
The mass or weight or a ruler would best be measured in grams.
The mass of a ruler would be measured in grams (g).

A ruler is used to measure length or distance, while a balance is used to measure weight or mass.
The weight of a ruler in newtons would depend on its mass and the acceleration due to gravity. Typically, a standard ruler would have a very small mass, so its weight in newtons would be very minimal, likely less than 1 newton.
The 50cm mark isn't necessarily the ruler's centre of mass where it will balance. If the ruler is not uniform (i.e. it has a hole in it) its centre of mass will not be exactly in the middle.
A balance will give you it's mass.
