Why are weight and mass used synonymously on Earth?
2 answers:
The difference between mass and time is the influence of the earth's gravitational force on objects
<h3><em>Further explanation</em></h3>In general, some people equate mass and weight.
Mass is one of the principal quantities, which is related to the matter in the matter, whereas weight is a force that leads to the center of the earth which is subject to the earth to matter (Earth's gravitational force)
So that the mass does not depend on the location of the object, while the weight can change depending on the position of the object
In international standards, the mass unit is kg while the weight is in units of newton
1 kg itself is the mass of a cylinder made of platinum-iridium
While the standard mass of an atom is determined according to the carbon-12 atomic mass of 12 atomic mass units
1 atomic mass unit comparable to 1.6605402.10-17 kg
Measuring the atomic mass using a mass spectrometer.
The mass itself can be measured by the arm balance while the weight is measured by the spring balance
One equation that can relate mass and force (weight) is
W = m.g
W = weight, N
m = mass, kg
g = gravity acceleration, m / s2

Given parameters:
Mass of sucrose = 5g
Density of sucrose = 1.12g/mL
Percentage of sucrose per liter of cane juice = 12%
Unknown:
Volume of cane juice needed = ?
We need to establish the volume - density relationship. Density is the mass of a substance per unit volume.
Mathematically;
Density =
Now solve for the volume of sucrose;
1.12g/mL =
Volume = = 4.46mL = 4.46 x 10⁻³L since 1000mL = 1L
Since 12% of 1 liter of cane juice is sucrose;
12% of x liter of cane juice = 4.46 x 10⁻³L
Volume of cane juice = 4.46 x 10⁻³ x = 0.037L
Volume of cane juice is 0.037L
