Answer:
a) Mass = 3.9 g
b) Mass = 0.395 g
Explanation:
Density is related to the mass and volume of a substance by the relation:
a) Given:
Volume = 4.00cm3
Density = 0.97 g/cm3
Based on equation (1)
b) Given:
Volume = 125 ml
Density = 3.16 g/L
1 ml = 0.001 L
Therefore, 125 ml = 0.125 L
Based on equation (1)
Answer:
Argon has a larger atomic number and a larger atomic mass.
I believe its B. <span>The chemical formula for water H2O represents 2 hydrogen and 1 oxygen in the compound. </span>
Explanation:
density=> ro=m/V
m=0,12kg
V=0,04m³=6,4.10^-5
=>0,12/6,4.10^-5=1875 kg/m³
Answer:
A .Exothermic
Explanation:
An exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction.
