Hello there!
How is density different from weight and mass you say? It's simple!
1. Unlike weight, density is composed of mass and volume.
2. By dividing the mass over the volume, you can determine an object's density, while weight is the product of mass and gravity.
Hope this helps :) if so, can I get Brainliest?
Answer:
2.173 moles of ethanol is presented in a 100.0g sample of ethanol .
Explanation:
The amount of substance that contains as many Particles as there are atoms in exactly 12g of carbon- '12 isotope is called 1 mole '= 46 u.
Use ideal gas law PV=nRT
at STP, pressure is 1atm and temperature is 273K (0 Celsius)
1×1.5L=n × 0.0821 × 273
n is moles and R is ideal gas law constant, always 0.0821
moles= 14.9422(6.02×10^23 molecules)=9.0×10^24 molecules
Water is an incomplete combustion as water is still produced by carbon monoxide and carbon are produced instead of carbon dioxide.
