Calculate the molarity of the solution?
this is my solution but it's wrong..can you make the correction for me please!
310 g C6H12O6 X 1 mole C6H12O6 / 180 g C6H12O6 / 0.800 L = 2.15 molarity
Answer:
The only thing i see wrong here is the significant figures. 310g is considered as 2 sig figs. So therefore, your answer would be 2.2M. 800. mL is considered as 3 sig figs because there is a decimal place behind the zero.
Molecular weight C6H12O6 = 180 g/mol
310 g / 180 = 1.72 moles of C6H12O6
V = 0.800 L
M = 1.72 / 0.800 = 2.15
This is correct!
Your solution is not wrong
Your answer is correct.
C6H12O6 Mol.mass = (12x 6) + (1 x 12) + (16 x 6)
= 72 + 12 + 96 = 180g/mol.
Mass/mol.mass = 310 ÷ 180 = 1.72 moles.
1.72moles = 800 mL
= (1.72moles ÷ 800mL) x 1,000 = 2.15mol/L = 2.15M
