The quantity that you would measure in kg, is mass.
Talja [164]3 years ago

SI units are the universally accepted standard units to measure quantity.

There are 7 basic parameters with each having an SI unit of its own

Kilograms are one of these SI units. Kilograms are used to measure Mass.

All the other units used to measure mass are derived from this basic unit.

eg:1000 g is equivalent to 1 kg

therefore quantity used to measure in kg is Mass

It takes one oxygen to combine with two hydrogen atoms to form water. What is the mass ratio of oxygen to hydrogen? 1 to 2 4 to
Rasek [7]

Answer:

8 to 1.

Explanation:

  • Oxygen combines with hydrogen atoms to form water according to the balanced equation:

<em>O₂ + 2H₂ → 2H₂O.</em>

It is clear that one mole of oxygen combines with two moles of hydrogen atoms to form 2 moles of water.

So, the molar ratio of oxygen to hydrogen is (1 to 2).

  • The mass of 1 mole of oxygen = (no. of moles)(molar mass) = (1 mol)(32.0 g/mol) = 32.0 g.
  • The mass of 2 moles of hydrogen = (no. of moles)(molar mass) = (2 mol)(2.0 g/mol) = 4.0 g.

<em>So, the mass ratio of oxygen to hydrogen (32.0 g/4.0 g) = (8: 1).</em>

6. What is the mass of the object if the net force acting on it was 356 N and the acceleration rate
Marina86 [1]

The mass of an object with a net force of 356N and an acceleration rate of 4m/s² is 89kg.

<h3>How to calculate mass?</h3>

The mass of an object can be calculated using the following formula:

F = ma

Where;

  • F = force (N)
  • m = mass (kg)
  • a = acceleration (m/s²)

m = F/a

m = 356/4

m = 89kg

Therefore, the mass of an object with a net force of 356N and an acceleration rate of 4m/s² is 89kg.
