Answer:
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. ... Density can also be expressed as kilograms per cubic metre (in metre-kilogram-second or SI units).
Explanation:
The formula of density is mass / volume
This means that
- high mass, low volume = high density
- high mass, high volume = so-so
- low mass, high volume = low density
From the graph shown,
D has the lowest density because it has low mass yet high volume.
Answer:
1
Explanation:
The numbers in front of the formulas (the coefficients) tell you how many moles of a substance are involved in a reaction.
If no coefficient is shown, we assume it is 1.
NOCl has no coefficient, so 1 mol of NOCl is in the balanced equation.
