The tool or instrument which is used to measure an object’s mass is electronic balance
Mass is a fundamental quantity
<h3>What is fundamental quantities?</h3>
Fundamental quantities can be defined as those physical quantities which forms the basic unit of measurement. They are the quantities upon which other quantities and units are derived from.
Mass is measured in kilograms (kg)
Other examples of fundamental quantities apart from mass are as follows:
- Length
- Time
- Amount of substances
- Luminous intensity
- Temperature
- Magnetic flux
So therefore, the tool or instrument which is used to measure an object’s mass is electronic balance

Answer:
300 mL
Explanation:
the unit formula of calcium phosphate is Ca3(PO4)2
molar mass of Ca3(PO4)2 = (3×40 + 2×31 + 8×16) g/mol = 310 g/mol
n = m/M = 35 g/(310 g/mol)
c = n/V
V = n/c = [35 g/(310 g/mol)]/0.375 mol/L
V = 0.30 L = 300 mL
In 1869 Russian chemist DIMITRI MENDELEEV started the development of the periodic table,arranging chemical elements by atomic mass. He predicted the discovery of other elements and left spaces open in his periodic table for them. HOPE THIS HELPSS HAVE A GREAT DAY <333
