Answer:
C
Explanation:
Calculate the number of moles of Al2O3 that are produced when 15 mol of Fe is produced
in the following reaction.
C) 45 mol
The correct answer is 1000 Kg/M³
Density of water =1-g/cm3.
We know 1- g= 10^-³ Kg
cm³ =(10^-2)³= 10^-6
Substituting we get
Density of water
= 1 x (1x10^-³)/10^-6 Kg/M³
= 1x10^3 = 1000 Kg/M³
<h3>
what is density?</h3>
Density is the mass of a material substance per unit volume. Density is defined as d = M/V, where d represents density, M is mass, and V is volume. Density is generally measured in grammes per cubic centimetre. Water, for example, has a density of 1 gramme per cubic centimetre, but Earth has a density of 5.51 grammes per cubic centimetre. Density is sometimes measured in kilos per cubic metre (in metre-kilogram-second or SI units). The density of air, for example, is 1.2 kilogrammes per cubic metre. Textbooks and handbooks list the densities of common solids, liquids, and gases.
