Answer:

Absolute error $= 0.001$

% Error $= 002$ 5

Explanation:

The absolute error is the the difference in the measured value and the actual value of a quantity.

Here the actual value is $5.0000$ grams

The measured value is $5.001$ grams

Absolute error

$5.001 - 5.000\\= 0.001$

Percent error

$= \frac{AE}{AV}$

Where AE stands for absolute error and AV stands for absolute value.

$= \frac{0.001}{5.000} * 100\\$

$= 0.02$ %

During a lab, you heat 1.62 g of a CoCl2 hydrate over a Bunsen burner. After heating, the final mass of the dehydrated compound

sashaice [31]

Answer is: formula of hydrate is CoCl₂· 6H₂O -c<span>obalt(II) chloride hexahydrate
</span>m(CoCl₂· xH₂O) = 1,62 g.
m(CoCl₂) = 0,88 g.
n(CoCl₂) = m(CoCl₂) ÷ M(CoCl₂)
n(CoCl₂) = 0,88 g ÷ 130 g/mol
n(CoCl₂) = 0,0068 mol.
m(H₂O) = 1,62 g - 0,88 g.
m(H₂O) = 0,74 g.
n(H₂O) = m(H₂O) ÷ m(H₂O)
n(H₂O) = 0,74 g ÷ 18 g/mol
n(H₂O) = 0,041 mol.
n(CoCl₂) : n(H₂O) = 0,0068 mol : 0,041 mol.
n(CoCl₂) : n(H₂O) = 1 : 6.
