The families, or groups, have similar properties, for example, the first group 1 are made of extremely reactive metals. They will also have similar boiling, melting, and conductivity. With valence electrons all in the same orbital (alkaline metals all have valence electrons in the s orbital)<span />
Answer:
i. Molar mass of glucose = 180 g/mol
ii. Amount of glucose = 0.5 mole
Explanation:
<em>The volume of the glucose solution to be prepared</em> = 500 
<em>Molarity of the glucose solution to be prepared</em> = 1 M
i. Molar mass of glucose (
) = (6 × 12) + (12 × 1) + (6 × 16) = 180 g/mol
ii.<em> mole = molarity x volume</em>. Hence;
amount (in moles) of the glucose solution to be prepared
= 1 x 500/1000 = 0.5 mole
I'm pretty sure that it's either 83.2% or 91.4%
