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
ZnCl2 is the chemical formula, hope this helps.
Answer:
C
Explanation:
I just think it is the right answer :) Sorry if I am wrong..
Physical looks at appearance e.g if its solid
chemical is more of what it contains and how it reacts e.g metals
