Your answer would be, I believe, The same number of decimal places as the least precise values!!!!
Hope that helps!!!
The earth is divided into "spheres", each with its own properties and characteristics. The sphere containing all of the solid ground and layers of the earth is known as the lithosphere (or geosphere).
Other spheres of the earth are the hydrosphere, the cryosphere, and the atmosphere.
Answer:
0.4429 m
Explanation:
Given that mass % of the ethanol in water = 2%
This means that 2 g of ethanol present in 100 g of ethanol solution.
Molality is defined as the moles of the solute present in 1 kilogram of the solvent.
Given that:
Mass of 
= 2 g
Molar mass of = 46.07 g/mol
The formula for the calculation of moles is shown below:
Thus,
Mass of water = 100 - 2 g = 98 g = 0.098 kg ( 1 g = 0.001 kg )
So, molality is:
<u>Molality = 0.4429 m</u>
<span>CO2 (carbon) is the main product that results from burning paper. The paper is the reactant
When paper burns in a fire, the reactants are mostly carbon (the main substance in the paper) and oxygen (from the air).Co2
If paper is loaded with CaCO3 such as cigarette paper, CaCO3 decompose in to CaO and CO2</span>
