  • The units used for mass were kilogram (kg)
  • The units used for volume were cubic metres (m³)
  • The units used for density were kilogram per cubic metres (kg/m3).

When carrying out a research or experiment in a laboratory, your data should be recorded using standard units.

These units are called S.I. units or International system of units. They are the globally-agreed system of measurement units.

The properties of an object with its SI unit include:

  • Mass: This is the quantity of matter that is found in an object which is always constant. The SI unit of mass is Kilogram (kg).
  • Volume: This measures the space occupied by an object. The SI unit of volume is cubic metres (m³).
  • Density: This is mass of a unit volume of an object. The SI unit of density is kilogram per cubic metres (kg/m3).

What is the frequency of red light with a wavelength of 645 nm?
marin [14]

Answer:

4.64E14

Explanation:

First convert 645 nm to m = 6.4500E-7m. The equation for finding v with these values is the speed of light/wavelength. so 2.998E8/6.4500E-7m.

so your v or frequency would equal 4.64E14

Fun fact you know this is visible light because the visible light range is within the E14 range.

A gas is at a pressure of 3.70 atm. What is this pressure in kilopascals?
Yanka [14]
Answer:
                =   374.90 kPa 

Calculation:
                  As we know atm and kiloPascal are related to each other as,

                                         1 atm  =  101.325 kPa
So,
                                    3.70 atm  =   X
Solving for X,
                                     X  = (3.70 atm × 101.325 kPa) ÷ 1 atm

                                     X  =  374.90 kPa

A compound has the empirical formula CH2O. If the compound’s molecular mass is 180 g/mol, determine the molecular formula of the
Umnica [9.8K]
The molecular formula will be a multiple of the empirical CH2O. One unit of CH2O has a mass of 12+2*1+16 = 30 g. This means that if our compound has a molecular mass of 180 g/mol, we can divide 180 / 30 = 6 units, and our compound has 6 units of CH2O. This means that its molecular formula is C6H12O6.
