## What are the 3 equations for density?

What are the three formulas for density?

• To work out density: p = m / V.
• To work out the mass: m = p x V.
• To work out the volume: V = m / p.

What is the meaning of mechanical accuracy?

Mechanical Accuracy: this refers to grammar, spelling and punctuation.

Why is density measured at 15 C?

Since the density of a liquid varies as its temperature changes, the scale is adjusted to a certain temperature, usually about 15 degrees C., at which determinations must be made. Its scale is adapted to liquids heavier or lighter than water.

### What is the density of a 36 g object?

Answer: Density of an object is 2.4 g/cm³.

What are mechanical errors?

Mechanical mistakes are those of orthography (spelling and capitalization) and punctuation. Everyone who writes in English makes such mistakes, whether native speaker or ESL student. In many cases mechanical errors are the consequence of quick writing where the focus is on the content rather than the form.

What is SI unit of molarity?

In chemistry, the most commonly used unit for molarity is the number of moles per liter, having the unit symbol mol/L or mol⋅dm−3 in SI unit. A solution with a concentration of 1 mol/L is said to be 1 molar, commonly designated as 1 M.

#### What is the density of a 700 kg object?

0.927 kg/m3

What are the three general classes of errors?

Generally errors are classified into three types: systematic errors, random errors and blunders.

Which material has the highest density?

Osmium

## What are the 4 basic units of the metric system?

The metric system is a system of measurement that uses the meter, liter, and gram as base units of length (distance), capacity (volume), and weight (mass) respectively.

What is standard density?

In physics, usually the density of water at the ice point (0°C), 0.99984 g cm-3; or the maximum density of water (at 4°C), 0.99997 g cm-3. In the U.S. Standard Atmosphere–1976, the density of air at a standard temperature of 15°C and a standard pressure of 1013.25 mb is 1225.00 g cm-3.

What are the types of errors in physics?

TYPES OF EXPERIMENTAL. Errors are normally classified in three categories: systematic errors, random errors, and blunders. Systematic errors are due to identified causes and can, in principle, be eliminated. Errors of this type result in measured values that are consistently too high or consistently too low.

### Does air density increase with altitude?

Air density is higher at lower altitudes. There is more space between air molecules at higher altitudes. There is less oxygen to breathe at the top of a high mountain than there is at sea level.

What is Densitys formula?

Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
