Using the ideal gas equation:
PV = nRT, we can form:
V/n = constant
Thus,
V₁/n₁ = V₂/n₂
n₂ = 2.3 x 85.5/50.5
= 3.89 moles
Alkali metals (metals ) group 1 - properties are ● they are good conductors of heat
● luster (shiny)
● malleable (can be broken down into thin sheets)
● ductile
●lose electrons to form (+) ions
Answer:
Explanation:
molar mass of any subtance in 1 litre water gives 1N solution
for NaOH molar mass =40 g
40g --- 1000ml ---1N
Xg---- 150 ----0.02
X= 40*150*0.02/1000*1 =0.12 g
Something that scientists study that is cold could be liquid nitrogen!
